<code snipped>

something to play around with

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class ButtonFrame extends JFrame
{
  JButton[] btns = new JButton[12];
  int treasureAt = (int)(Math.random()*btns.length);
  public ButtonFrame()
  {
    super ("Treasure Map");
    setLayout( new FlowLayout() );
    ButtonHandler handler = new ButtonHandler();
    for(int x= 0, y = btns.length; x < y; x++)
    {
      btns[x] = new JButton(""+(x+1));
      btns[x].addActionListener(handler);
      add(btns[x]);
    }
  }
  class ButtonHandler implements ActionListener
  {
    public void actionPerformed( ActionEvent event )
    {
      String msg = "No treasure here: %s";
      int x = 0, y = btns.length;
      for(x = 0; x < y; x++) if(btns[x] == event.getSource()) break;
      if(x == treasureAt) msg = "Bingo!! at: %s";
      JOptionPane.showMessageDialog(ButtonFrame.this,String.format(msg,event.getActionCommand()));
    }
  }
  public static void main(String args[])
  {
    ButtonFrame buttonFrame = new ButtonFrame();
    buttonFrame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
    buttonFrame.setSize( 300, 275 );
    buttonFrame.setVisible( true );
  }
}
