不清楚你需要的是哪些功能的，我这里有个计算器的小程序，解释的蛮清楚的你可以看看：
package Calculator;
//以下是所需要的一些包
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Calculator extends JFrame {//继承JFrame

private Container container; //添加一个容器
private GridBagLayout layout; //一个灵活的布局管理器
private GridBagConstraints constraints; //每个由 GridBagLayout 管理的组件都与 GridBagConstraints 的实例相关联
private JTextField displayField; //计算结果显示区，单行文本框
private String lastCommand; //保存+,-,*,/,=命令
private double result; //保存计算结果
private boolean start; //判断是否为数字的开始

public Calculator() {

super("Calculator"); //调用父类构造函数
container=getContentPane(); //返回此窗体的 contentPane 对象
layout=new GridBagLayout(); //实例化布局
container.setLayout(layout); //设置此容器的布局管理器
constraints=new GridBagConstraints(); //用来布局的
start=true; //初始的时候设置这是数字的开头
result=0; //初始结果为0
lastCommand = "="; //保存命令为等号
displayField=new JTextField(20); //长度为20的文本编辑框
displayField.setHorizontalAlignment(JTextField.RIGHT); //右对齐
constraints.gridx=0; //列
constraints.gridy=0; //行 指定第0行0列的单元格
constraints.gridwidth=4; //某一行的单元格数
constraints.gridheight=1; //某一列的单元格数目
constraints.fill=GridBagConstraints.BOTH;//当组件的显示区域大于它所请求的显示区域的大小时使用此字段
//确定是否调整组件大小,使组件完全填满其显示区域
constraints.weightx=100; //加权值，设置显示比例
constraints.weighty=100; //同上
layout.setConstraints(displayField,constraints);//设置要显示的约束，对文本编辑框使用constraints约束
container.add(displayField); //在容器中添加文本框
ActionListener insert = new InsertAction(); //添加一个监听器来监听事件
ActionListener command = new CommandAction();//同上，作用如字面意思
addButton("Backspace",0,1,2,1,insert); //添加按钮，调用下面的方法
addButton("C",2,1,2,1,insert);//添加按钮，下同，各个参数的意思看下面的方法
addButton("7",0,2,1,1,insert);
addButton("8",1,2,1,1,insert);
addButton("9",2,2,1,1,insert);
addButton("/",0,6,1,1,command);
addButton("4",0,3,1,1,insert);
addButton("5",1,3,1,1,insert);
addButton("6",2,3,1,1,insert);
addButton("*",1,6,1,1,command);
addButton("1",0,4,1,1,insert);
addButton("2",1,4,1,1,insert);
addButton("3",2,4,1,1,insert);
addButton("-",2,6,1,1,command);
addButton("0",0,5,1,1,insert);
addButton("负数",1,5,1,1,insert);
addButton(".",2,5,1,1,insert);
addButton("+",3,6,1,1,command);
addButton("=",3,2,1,4,command);
setSize(300,300);//设置窗口大小前面是宽后面是长
setVisible(true);//设置窗口可见
}

private void addButton(String label,int row,int column,int with,int height,ActionListener listener)
{
JButton button=new JButton(label);//实例化一个按钮
constraints.gridx=row;//在第row列，注意这里把行和列搞反了
constraints.gridy=column;//第column行
constraints.gridwidth=with;//宽
constraints.gridheight=height;//长
constraints.fill=GridBagConstraints.BOTH;
button.addActionListener(listener);//为每一个按钮添加监听器用来监听事件
layout.setConstraints(button,constraints);
container.add(button);//添加到容器中
}

private class InsertAction implements ActionListener {

public void actionPerformed(ActionEvent event) {

String input=event.getActionCommand();
if (start) { //刚刚开始的时候,可以添加负号，其他时候不行
displayField.setText("");
start=false;
if(input.equals("负数"))
displayField.setText("-");
}

if(!input.equals("负数")) {
if(input.equals("Backspace")) {
String str=displayField.getText();
if(str.length()>0)
displayField.setText(str.substring(0,str.length()-1));
}
else if(input.equals("C")) {
displayField.setText("0");
start=true;
}else
displayField.setText(displayField.getText()+input);
}
}
}

private class CommandAction implements ActionListener { //对于 + - * / =的处理

public void actionPerformed(ActionEvent event) {
String command=event.getActionCommand();
calculate(Double.parseDouble(displayField.getText()));//计算,这里需要将字符串转化为双精度
lastCommand=command;
start=true;
}
}

public void calculate(double x) { //计算
if (lastCommand.equals("+")) result+= x;
else if (lastCommand.equals("-")) result-=x;
else if (lastCommand.equals("*")) result*=x;
else if (lastCommand.equals("/")) result/=x;
else if (lastCommand.equals("=")) result=x;
displayField.setText(""+ result);
}

public static void main(String []args) {
Calculator calculator=new Calculator();
calculator.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//点击关闭按钮的时候退出程序
}
}
