Trying to compile a GUI program with ActionEvent and Color/Graphics

Question

Hey, I am trying to compile a program that where I press a button it designs/displays a picture. I have the first part that shows the button, but I can''t get the second part of it. Any suggestions on what to do? Here is the part of the code that I am unsure about, the idea is to get that to design a picture:
private class ButtonHandler implements ActionListener
          public void actionPerformed( ActionEvent event )
     }

Answer 1

Heres the code in order to give a better idea of what I am trying to do:
import java.awt.FlowLayout;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.JButton;
public class Game extends JFrame
     private JLabel greeting; // greets user and gives initial instructions
     private JButton startGame; // start game button
     private JButton highScore; // displays high scores
     private JButton exitGame; // exits game
     // adds buttons to JFrame
     public Game()
          super( "Game" );
          setLayout( new FlowLayout() ); // set frame layout
          greeting = new JLabel( "Make selection..." );
          add( greeting );           
          startGame = new JButton( "Start Playing" );
          add( startGame );
          highScore = new JButton( "View High Scores" );
          add( highScore );
          exitGame = new JButton( "Exit Game" );
          add( exitGame );
          ButtonHandler handler = new ButtonHandler();
          startGame.addActionListener( handler );
     private class ButtonHandler implements ActionListener
          public void actionPerformed( ActionEvent event )
          public void paintComponent( Graphics g )
super.paintComponent( g );
g.setColor( Color.RED );
g.fillOval( 10, 10, 200, 200 );
}
