import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class BroderLayoutDemo {
private static void showGUI(){
JFrame frame= new JFrame("flowLayoutDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel=new JPanel();
JPanel panelN=new JPanel();
panelN.setBackground(Color.YELLOW);
JPanel panelS=new JPanel();
panelS.setBackground(Color.PINK);
JPanel panelC=new JPanel();
panelC.setBackground(Color.BLUE);
frame.setSize(300, 200);
frame.setLocation(300, 200);
panel.setLayout(new BorderLayout());
JButton button1=new JButton("North1");
JButton button2=new JButton("North2");
JButton button3=new JButton("South1");
JButton button4=new JButton("South2");
JButton button5=new JButton("Center1");
JButton button6=new JButton("Center2");
JButton button7=new JButton("Center3");
panel.add(panelC,"Center");
panel.add(panelN,"North");
panel.add(panelS,"South");
panelN.setLayout(new FlowLayout());
panelN.add(button1);
panelN.add(button2);
panelS.setLayout(new FlowLayout());
panelS.add(button3);
panelS.add(button4);
panelC.setLayout(new GridLayout(2,2));
panelC.add(button5);
panelC.add(button6);
panelC.add(button7);
frame.add(panel);
frame.add(panel);
frame.setVisible(true);
}
public static void main(String args[]){
showGUI();
}
}
颜色有点不太准，可以自己下个工具调一下，写的好辛苦，希望能给分啊

有难度么？
package Test2;

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.GridLayout;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class TestJFrame {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
JFrame jf = new JFrame("测试");

JPanel jp1 = new JPanel();
jp1.setLayout(new FlowLayout(FlowLayout.CENTER));
jp1.add(new JButton("Notrh1"));
jp1.add(new JButton("Notrh2"));

JPanel jp2 = new JPanel();
jp2.setLayout(new GridLayout(2,2));
jp2.add(new JButton("Center1"));
jp2.add(new JButton("Center2"));
jp2.add(new JButton("Center3"));

JPanel jp3 = new JPanel();
jp3.setLayout(new FlowLayout(FlowLayout.CENTER));
jp3.add(new JButton("South1"));
jp3.add(new JButton("South2"));

jp1.setBackground(Color.YELLOW);
jp2.setBackground(Color.BLUE);
jp3.setBackground(Color.RED);

jf.add(jp1,BorderLayout.NORTH);
jf.add(jp2,BorderLayout.CENTER);
jf.add(jp3,BorderLayout.SOUTH);

jf.setSize(300, 400);
jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jf.setVisible(true);

}

}
