JDialog, form, GridBagLayout

Question

I am working on a form like shown in the Java tutorial: "How to Use SpringLayout", http://java.sun.com/docs/books/tutorial/uiswing/layout/spring.html -> "SpringForm".
I would like to use GridBagLayout. Here is my code:
public class TestDialog extends JDialog {
     private JPanel infoPanel;
     private JLabel infoLabel, nameLabel;
     private JTextField nameField;
     public TestDialog() {
          Dimension dim_dialog = new Dimension(200, 100);
          JPanel pane = new JPanel(new GridBagLayout());
          GridBagConstraints c = new GridBagConstraints();
          c.fill = GridBagConstraints.HORIZONTAL;
          infoPanel = new JPanel();
          c.weightx = 0.5;
          c.gridx = 0;
          c.gridy = 0;
          pane.add(infoPanel, c);
          infoLabel = new JLabel("Some information...");
          infoPanel.add(infoLabel);
          nameLabel = new JLabel("Name:");
          c.weightx = 0.5;
          c.gridx = 0;
          c.gridy = 1;
          pane.add(nameLabel, c);
          nameField = new JTextField(20);
          c.weightx = 0.5;
          c.gridx = 1;
          c.gridy = 1;
          pane.add(nameField, c);
          add(pane);
          setPreferredSize(dim_dialog);       
        setDefaultCloseOperation( DISPOSE_ON_CLOSE );
          pack();
}As you can see, the layout is not correct; I would like to get a layout like in "SpringForm" - plus a JLabel at the top where I can write some informative text...
Can't figure it out at the moment how to use GridBagLayout for that :-/
Thanks!

}Did you expect this ?
