Display a schematic view with icons (jpg, gif, etc).

Question

I'm trying to display a schematic view and use icons to represent the difference objects in this schematic view.
For example: to show a 3 phones conference call. The description will be the phone number (or person's name) and the icon will be the person's face or company logo.
I have tried to use JLabel, and JButton but then I have to use a Layout. Without a layout the are one-on-top of another.
I tried to use setLocation and it doesn't look to have any effect on the location of JLabel or JButton.
The following is my code:
import java.awt.Container;
import java.awt.Insets;
import java.awt.Point;
import java.awt.Dimension;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
* ShowIcons.java is a 1.4 application that requires no other files.

public class ShowIcons {
    public static void addComponentsToPane(Container pane) {
        ImageIcon iconHE, iconCPE, iconNode, iconDemo;
        Point point1, point2, point3;
        pane.setLayout(null);
        iconHE = createImageIcon(NODE_HE_ICON);
        iconNode = createImageIcon(NODE_ICON);
        iconCPE = createImageIcon(NODE_CPE_ICON);
        iconDemo = createImageIcon(NODE_CPE_ICON);
        JButton b1 = new JButton(HE_TEXT, iconHE);
        JButton b2 = new JButton(NODE_TEXT, iconNode);
        JButton b3 = new JButton(CPE_TEXT, iconCPE);
        point1 = new Point(0, 500);
        point2 = new Point(500, 0);
        point3 = new Point(500, 500);
        b1.setLocation( point1 );
        b2.setLocation( point2 );
        b3.setLocation( point3 );
        pane.add(b3);
        pane.add(b2);
        pane.add(b1);
//        pane.add(iconDemo);
        Insets insets = pane.getInsets();
        Dimension size = b1.getPreferredSize();
        b1.setBounds(25 + insets.left, 5 + insets.top,
                     size.width, size.height);
        size = b2.getPreferredSize();
        b2.setBounds(55 + insets.left, 40 + insets.top,
                     size.width, size.height);
        size = b3.getPreferredSize();
        b3.setBounds(150 + insets.left, 15 + insets.top,
                     size.width + 50, size.height + 20);
    /** Returns an ImageIcon, or null if the path was invalid. */
    protected static ImageIcon createImageIcon(String path) {
        java.net.URL imageURL = ShowIcons.class.getResource(path);
        if (imageURL == null) {
            System.err.println("Resource not found: "
                               + path);
            return null;
        } else {
            return new ImageIcon(imageURL);
    }   //  End of Method protected static ImageIcon createImageIcon(String)
     * Create the GUI and show it.  For thread safety,
     * this method should be invoked from the
     * event-dispatching thread.
    private static void createAndShowGUI() {
        //Make sure we have nice window decorations.
        JFrame.setDefaultLookAndFeelDecorated(true);
        //Create and set up the window.
        JFrame frame = new JFrame("AbsoluteLayoutDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        //Set up the content pane.
        addComponentsToPane(frame.getContentPane());
        //Size and display the window.
        Insets insets = frame.getInsets();
        frame.setSize(300 + insets.left + insets.right,
                      125 + insets.top + insets.bottom);
        frame.setVisible(true);
    public static void main(String[] args) {
        //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
    public static final String NODE_HE_ICON = "images/shop_icon_esd_110.gif";
    public static final String NODE_CPE_ICON = "images/Default_feature1.gif";
    public static final String NODE_ICON = "images/icondesktop.gif";
    public static final String HE_TEXT = "Headent";
    public static final String CPE_TEXT = "CPE";
    public static final String NODE_TEXT = "10.0.0.10";
}Anyone has an idea??
