//代码写得不错，不过布局有点乱，呵呵，而且你可以设计当点到textfield
//的时候自动清除里面的字，这样会更方便一点

代码写的非常混乱。
权宜之计的改法：
1 在GuessNumber类中添加成员变量，
private static int GuessCount =0;
private static Label DisplayCount=new Label(" ");
2 在actionPerformed中添加
GuessCount++;
DisplayCount.setText("Guessed "+GuessCount);
3 在actionPerformed中添加
GuessCount = 0;
