Graphics display problem need help.

Question

I have a class called "Window" that obviously sets up my window, I also have a class called "IconGen" that should generate an Icon. Both of the class codes are posted below but for some reason I cannot get the graphic to show up in the frame. Can anyone lend a helping hand??
Window code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Window extends JFrame{
     JPanel jp = new JPanel();
     public void setupJFrame(){
          setBackground(Color.gray);
          setSize(200,200);
          setVisible(true);
          addWindowListener     (new WindowAdapter(){
               public void windowClosing(WindowEvent e){
                    System.exit(0);
     public void setupJPanel(){
     jp.setBackground(Color.white);
     getContentPane().add(jp);
     setVisible(true);}
     public static void main(String args[]){
          Window w = new Window();
          IconGen i = new IconGen();
          w.setupJFrame();
          w.setupJPanel();
     w.getContentPane().add(i);
IconGen code:
import java.awt.*;
import java.awt.geom.*;
import javax.swing.*;
public class IconGen extends JComponent{
private     Color salmon = new Color(255,128,128);
private     Polygon p = new Polygon();
public Polygon IconGen(){
               int[] x = {75,125,75,25};
               int[] y = {25,75,125,75};
               int pts = 4;
               Polygon p = new Polygon(x,y,pts);
     return(p);
public void paint(Graphics g){
               super.paint(g);
               g.setColor(salmon);
               g.translate(15,15);
               g.fillPolygon(p);
}

Hi the constructor of IconGen looks like a problem, and it should subclass JPanel not JComponent.
Here's a working example:
import java.awt.*;
import javax.swing.*;
public class TestFrame extends javax.swing.JFrame {
/** Creates new form TestFrame */
public TestFrame() {
initComponents();
this.getContentPane().add(new MyIcon());
/** This method is called from within the constructor to
* initialize the form.
* WARNING: Do NOT modify this code. The content of this method is
* always regenerated by the Form Editor.
private void initComponents() {
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
exitForm(evt);
pack();
/** Exit the Application */
private void exitForm(java.awt.event.WindowEvent evt) {
System.exit(0);
* @param args the command line arguments
public static void main(String args[]) {
new TestFrame().show();
// Variables declaration - do not modify
// End of variables declaration
class MyIcon extends JPanel{
Color salmon = new Color(255,128,128);
int[] x = {75,125,75,25};
int[] y = {25,75,125,75};
int pts = 4;
Polygon p = new Polygon(x,y,pts);
public void paint(Graphics g){
g.setColor(salmon);
g.fillPolygon(p);
