关于java swing里的对话框问题

import java.awt.*;
import javax.swing.*;
public class StudentInfo
{
JLabel lblinfo;//显示学生录入的标签
JLabel lblname,lblsex,lblbirth,lblpro,lbltype,lblscore;
JTextField txtname,txtbirth,txtpro,txtscore;//输入文本框
JRadioButton btnsexw,btnsexm;//按钮定义
JComboBox cmtype;
JButton btnSubmit,btnCancel;
public StudentInfo()
{ //初始化标签
String str[]=new String[]{"单招","非单招"};
lblinfo=new JLabel("学生基本信息录入");
lblname=new JLabel("学生姓名");
lblsex=new JLabel("学生性别");
lblbirth=new JLabel("出生日期");
lblpro=new JLabel("所学专业");
lbltype=new JLabel("是否单招");
lblscore=new JLabel("计算机考试成绩");
//输入文本框的初始化
txtname=new JTextField(30);
txtbirth=new JTextField(30);
txtpro=new JTextField(30);
txtscore=new JTextField(30);
//初始化单选按钮
btnsexm=new JRadioButton("男");
btnsexw=new JRadioButton("女");
//initial comblblx
cmtype=new JComboBox(str);// 单招和非单招！
//initial button
btnSubmit=new JButton("确定");
btnCancel=new JButton("取消");
//
JFrame jf=new JFrame("学生信息录入");
JPanel jp=new JPanel();

Container c=jf.getContentPane();
c.add(jp);

jp.add(lblinfo);
jp.add(lblname);
jp.add(txtname);
jp.add(lblsex);
jp.add(btnsexm);
jp.add(btnsexw);
jp.add(lblbirth);
jp.add(txtbirth);
jp.add(lblpro);
jp.add(txtpro);
jp.add(lbltype);
jp.add(cmtype);
jp.add(lblscore);
jp.add(txtscore);
jp.add(btnSubmit);//确定
jp.add(btnCancel);//取消
jf.setSize(200,600);
jf.setVisible(true);//可见性
}
//class l implements ActionListener
//{
// public void actionPerformed(ActionEvent e)
// {

// }

//}

public static void main(String s[])
{
new StudentInfo();
}
}
用java编的一个框架，向实现 点击确定后弹出个对话框显示刚才输入的内容 我不会事件处理！请高手帮帮忙
我的想法是不是还得再建个面板把输入的内容放到这个新建的面板上,等点确定后就弹出这个面板？我的这个思路对吗？我刚刚学习swing不明白？

btnSubmit.addActionListener(this);
jp.add(btnCancel);//取消
btnCancel.addActionListener(this);
jf.setSize(200,600);
jf.setVisible(true);//可见性
}

public static void main(String s[])
{
new StudentInfo();
}

public void actionPerformed(ActionEvent e)
{
if(e.getSource()==btnSubmit)
{
String s=str[0];//这里你要判断 是str[0]还是str[1]
//单招还是非单招
JOptionPane.showMessageDialog(null,s+txtname.getText()+txtbirth.getText()+txtpro.getText()+txtscore.getText(), "标题", JOptionPane.PLAIN_MESSAGE);
}

}
}
只是给你了个例子 具体的自己再研究一下
