GUI JLabel Problem

Question

Hello, I am a noob and i will admit it. I have been at it for a few hours now trying to figure out how to....
1.) Add JLabels to a GUI with a Background painted on it using the paint(); method without it being retarded
2.) Update the gui with paint(); and have it not flash (I've tried using update with double buffer)
Can someone lead me in the right direction?
Here's my code..
import java.util.*;
import java.net.*;
import javax.swing.*;
import java.io.*;
import javax.swing.JOptionPane;
import java.awt.*;
import java.awt.event.*;
public class PingPongGUI extends JFrame implements KeyListener
     private Image dbImage;
     private Graphics dbg;
     double p1score=0;
     double p2score=0;
     String p1scoreStr="";
     String p2scoreStr="";
     ImageIcon backImage = new ImageIcon("ping-pong-medium.jpg");
     JLabel Player1L = new JLabel("Test Label");
    public PingPongGUI() throws Exception
          this.setFocusable(true);
         this.addKeyListener(this);
        setTitle("Ping Pong Leagues (Beta Version 1.0) : Developed by ME. || ANDREW IS A BOCE!");
        setSize(800, 600);
        setResizable(false);
        Container pane = getContentPane();
        pane.setLayout(null);
          //Adding stuff to the GUI
          //pane.add(Player1L);
          //GUI Preferences
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    public static void main(String[] args) throws Exception,AWTException,IOException
        PingPongGUI PPGUI = new PingPongGUI();
    public void paint(Graphics g)
          super.paint(g);
          //Drawing the scores on the window
          g.drawImage(backImage.getImage(), 0, 0, 800, 600, null);
          java.awt.Font font = new java.awt.Font("Arial Narrow",1,20);
          //Set Labels Overtop of background image
          Player1L.setFont(font);
          Player1L.setForeground(Color.blue);
          Player1L.setSize(40, 40);
          Player1L.setLocation(30, 50);
          //Player1L.setOpaque(true);
          Player1L.setVisible(true);
     public void update(Graphics g)
               //Double Buffering to insure no flash when movment occurs
               // initialize buffer
               if (dbImage == null)
                    dbImage = createImage (this.getSize().width, this.getSize().height);
                    dbg = dbImage.getGraphics ();
               // clear screen in background
               dbg.setColor (getBackground ());
               dbg.fillRect (0, 0, this.getSize().width, this.getSize().height);
               // draw elements in background
               dbg.setColor (getForeground());
               paint (dbg);
               // draw image on the screen
               g.drawImage (dbImage, 0, 0, this);

Answer 1

You will benefit greatly by going through the Sun graphics tutorials. There you will learn not to paint directly to a JFrame (similar for JApplet) but instead to a JComponent or JPanel. Also, you appear to be using your paint method to do program logic and this is definitely a very bad thing to do as you cannot control when a paint method will be called. Again, the tutorials should help you with this too.
