java写五子棋 关于鼠标事件的问题

初学者，自己尝试编写人人对战的五子棋。
但是鼠标事件弄不好。目前写成下面这个样子，却达不到目的，也没什么办法，请高人指教。
源代码如下：import java.awt.event.*;
import java.awt.* ;
import javax.swing.* ;
import java.lang.* ;

class Qipan extends JFrame implements MouseListener,MouseMotionListener{
Qipan(String title){
this.setTitle(title);
this.setSize(580,630);
this.setLocation(225,50);
this.setBackground(Color.WHITE);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

Container contentPane=getContentPane();
contentPane.addMouseListener(this);
contentPane.addMouseMotionListener(this);

}

static int zx=0,zy=0;
//画棋盘
public void paint(Graphics g){
super.paint(g);
for(int i=40;i<=540;i=i+20){
g.setColor(Color.black);
g.drawLine(i,80,i,580);
}
for(int i=80;i<=580;i=i+20){
g.setColor(Color.black);
g.drawLine(40,i,540,i);
}

int i,j;

g.drawString("游戏开始：",40,60);
Qizi q = new Qizi();
Xiaqi x = new Xiaqi();
int label=1;

int sign=0;
int gezi[][] = new int[33][33];
for(int m=4;m<30;m++)
for(int n=4;n<30;n++)
gezi[m][n]=0;
while(sign==0){

switch(label){
case 1:g.clearRect(350,60,100,20);
g.drawString("请红方落子...",300,60);

i=zx/20+2;
j=zy/20;
while(gezi[i][j]==0){
gezi[i][j]=1;
q.huaqizi(g,zx,zy,Color.red);
sign=x.panduan(i,j);
label=2;
}break;
case 2:g.clearRect(350,60,100,20);
g.drawString("请绿方落子...",300,60);

i=zx/20+2;
j=zy/20;
while(gezi[i][j]==0){
gezi[i][j]=1;
q.huaqizi(g,zx,zy,Color.green);
sign=x.panduan(i,j);
label=1;
}
}
}
//弹出游戏结束对话框
if(sign==1) {
JOptionPane.showMessageDialog(null,
"红方获胜!!!",
"Game Over !", JOptionPane.ERROR_MESSAGE);
}
else{
JOptionPane.showMessageDialog(null,
"绿方获胜!!!",
"Game Over !", JOptionPane.ERROR_MESSAGE);
}
//结束游戏
System.exit(0) ;
}
public void mousePressed(MouseEvent e){

zx=e.getX();
zy=e.getY();

}
public void mouseEntered(MouseEvent e){ }
public void mouseExited(MouseEvent e){ }
public void mouseClicked(MouseEvent e){ }
public void mouseReleased(MouseEvent e){ }
public void mouseMoved(MouseEvent e){ }
public void mouseDragged(MouseEvent e){ }

}
//画棋子
class Qizi{
int x;
int y;
Color z;
public void huaqizi(Graphics g,int x,int y,Color z){
g.setColor(z);
g.fillOval(x,y,14,14);
}
}
public class Test extends JFrame{
public static void main(String args[]){
Qipan q = new Qipan("欢迎使用bluebottle的五子棋（测试版）");
q.setVisible(true);
}
}
由于程序太长 ，我把Xiaqi类和里面的判断方法puanduan()省略了……

我也是初学者，这是我刚刚编写的五子棋源程序，希望对你有帮助，也请多多指教。

这个你到网上下一个，看看别人的，你就会写了，主要的就是鼠标拖动问题
