Swing Components not displaying in a JFrame

Question

Hi,
I have a JFrame with a couple of JLabels, JButtons etc. and a Choice Combo Box
my problem is that when i run the program the only component that gets displayed at first is Choice and in order for me to see the swing components i have to roll over them with my mouse and the JLabels dont even display when i do that..
Does anyone know how i can fix this please?
here is my code
import java.awt.*;
import java.awt.event.*;
import java.lang.*;
import java.awt.Image.*;
import java.io.*;
import java.net.*;
public class ImageViewerAnim extends JFrame {
     private JLabel perc, scale;
     private JTextField inPercent;
     private JButton draw, muteOn;
     private JPanel sPanel;
     private String[] pics = {"Earth", "Moon", "Jupiter", "Pluton", "Neptun"};
     private String[] picsFile = {"images/earth.gif", "images/moon.gif", "images/jupiter.jpg", "images/pluton.jpg", "images/neptun.jpg"};
     private String[] soundsFile = {"sounds/tada.wav", "sounds/notify.wav", "sounds/ding.wav", "sounds/chimes.wav", "sounds/chimes.wav"};
     private Choice ch;
     private Image pic;
     private AudioClip sound = null;
     private int scaleAm = 0;
     private int origScale = 500;
     private int finalScale = 0;
     private boolean proceed = true;
     public ImageViewerAnim() {
          Container c = getContentPane();
          c.setLayout(new BorderLayout());
          sPanel = new JPanel();
          ch = new Choice();
          for(int i = 0; i < pics.length; ++i) {
               ch.add(pics);
          scale = new JLabel("Scale");
          perc = new JLabel("%");
          inPercent = new JTextField(5); // scale value input field
          draw = new JButton("Draw");
          draw.setBorder(BorderFactory.createEtchedBorder());
          draw.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    int index = 0;
                    index = ch.getSelectedIndex();
                    pic = null;
                    repaint();
                    pic = (Toolkit.getDefaultToolkit().getImage(picsFile[index]));
                    try{
                    File f = new File(soundsFile[index]);
                    sound = Applet.newAudioClip(f.toURL());
                    }catch(MalformedURLException mfe) {
                         mfe.printStackTrace();
                    if(!inPercent.getText().equals("")) {
                         scaleAm = Integer.parseInt(inPercent.getText()); // get the scale amount from the user
                         finalScale = ((origScale * scaleAm)/100); // calculate the final scale amount based on what the user entered
                    }else {
                         finalScale = origScale; // default to original size of the image if no value for scale was entered
                    // creates a scaled instance of an image and takes the amount of scale as an argument
                    repaint();
                    sound.loop();
          muteOn = new JButton("Mute On");
          muteOn.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    sound.stop();
                    muteOn.setText("MuteOff");
          sPanel.add(ch);
          sPanel.add(scale);
          sPanel.add(inPercent);
          sPanel.add(perc);
          sPanel.add(draw);
          sPanel.add(muteOn);
          c.add(sPanel, BorderLayout.SOUTH);
          repaint();
public void paint(Graphics g) {
     if(pic!=null) {
          g.drawImage(pic,0,0,this);
public static void main(String args[]) {
     ImageViewerAnim app = new ImageViewerAnim();
     app.setSize(500,500);
     app.setVisible(true);
     app.setDefaultCloseOperation(EXIT_ON_CLOSE);
     app.show();
thank you in advance
