Read this section from the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/14painting/index.html]Custom Painting.
Here is a simple example:
import java.awt.*;
import javax.swing.*;
public class FaceComponent
    public static void main(String args[])
        JPanel swing = new JPanel()
            public void paintComponent(Graphics g)
                 super.paintComponent(g);
                g.drawArc( 100, 45, 80, 80, 0, 360);
                g.setColor( Color.blue );
                g.drawArc( 120, 70, 10, 10, 0, 360);
                g.setColor( Color.blue );
                g.drawArc( 150, 70, 10, 10, 0, 360);
                g.setColor( Color.magenta );
                g.drawLine ( 140, 85, 140, 100 );
                g.setColor( Color.red );
                g.drawArc ( 110, 55, 60, 60, 0, -180 );
        swing.setPreferredSize( new Dimension(200, 200) );
        JFrame frame = new JFrame();
        frame.getContentPane().add( swing );
        frame.pack();
        frame.setVisible( true );
}
