Adding CheckBox and Text as child of a tree

Question

I want to have the following as the child of a tree :
**CheckBox[reference of CheckBox]+some text
example:
checkbox text1
checkbox text2
checkbox text3
I am unable to add both check box and text as the child of the tree.
My nodes are generated at run time so number of checkboxes will be known only at run time.
plz tell how can i achieve this functionality.
thanx

Just a small hint (The checkbox is not working yet - but shown):
import java.awt.Component;
import javax.swing.JCheckBox;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTree;
import javax.swing.tree.DefaultTreeCellRenderer;
public class CheckboxTreeRenderer extends DefaultTreeCellRenderer {
     @Override
     public Component getTreeCellRendererComponent(JTree tree, Object value,
                                                                 boolean sel, boolean expanded,
                                                                 boolean leaf, int row, boolean hasFocus) {
               JPanel p = new JPanel();
               p.add(new JCheckBox("Hallo " + row));
               p.add(new JLabel(value.toString()));
               return p;
import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTree;
public class CheckboxTreeFrame extends JFrame {
     public CheckboxTreeFrame(){
          super("A Checkboxtree");
          JTree t = new JTree(new String[]{"1", "2", "3"});
          t.setCellRenderer(new CheckboxTreeRenderer());
          JScrollPane p = new JScrollPane(t);
          add(p, BorderLayout.CENTER);
     public static void main(String [] args){
          CheckboxTreeFrame tf = new CheckboxTreeFrame();
          tf.setSize(200,300);
          tf.setDefaultCloseOperation(EXIT_ON_CLOSE);
          tf.setVisible(true);
}
