What component Should I use?, Jpanel doesn't work

Question

Hi
I need a program that has a window that can go fullscreen and windowed (I did that with a Jframe in fullscreen mode with a jpnale and a 800x600 Jpanel and destroying them with an object that maneges them), I did it with a jframe that contained a Jpanel, I used a Jpanel to avoid the flickering on the screen but I also need to change the font type and the font size, but the setFont on the Jpanel doesn't change the font (as I have realized and also read here [http://forum.java.sun.com/thread.jspa?forumID=257&threadID=150588] ), so I'm lost, I might have to redo the whole thing, but I just wanted to know what component should I use for a window that is going to have custom graphics and need diffrent fonts and diffrent font sizes and work in fullscreen without flickering
Thank you for your attention, I would aprecciate any help given

for example:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSlider;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
public class JPanelFont extends JPanel
  private Font font = getFont();
  private String myString = "Fubars Rule";
  private int fontSize = font.getSize();
  private JSlider slider = new JSlider(0, 100, fontSize);
  public JPanelFont()
    setPreferredSize(new Dimension(620, 250));
    setLayout(new BorderLayout());
    JPanel inputPanel = createInputPanel();
    add(inputPanel, BorderLayout.SOUTH);
  private JPanel createInputPanel()
    JPanel ip = new JPanel();
    slider.setMajorTickSpacing(20);
    slider.setMinorTickSpacing(5);
    slider.setPaintTicks(true);
    slider.setPaintLabels(true);
    ip.add(slider);
    slider.addChangeListener(new ChangeListener()
      public void stateChanged(ChangeEvent evt)
        fontSize = (Integer)slider.getValue();
        repaint();
    return ip;
  @Override
  protected void paintComponent(Graphics g)
    Graphics2D g2 = (Graphics2D)g;
    Object originalHint = g2.getRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING);
    g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
    super.paintComponent(g2);
    myPaint(g2);
    g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, originalHint);
  private void myPaint(Graphics2D g2)
    font = font.deriveFont(Font.BOLD, fontSize);
    g2.setFont(font);
    g2.drawString(myString, 20, 100);
  private static void createAndShowUI()
    JFrame frame = new JFrame("Dynamic JPanel Font");
    frame.getContentPane().add(new JPanelFont());
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
  public static void main(String[] args)
    java.awt.EventQueue.invokeLater(new Runnable()
      public void run()
        createAndShowUI();
