I found it.  It won't work quite as you have specified as it only allows 
one border per JComponent.  I've got a couple of ideas though, I'll get 
back to you.

public class test extends JPanel {
     JLabel l1,l2;
     JTextField tf1,tf2;

     public test() {
         super(new GridBagLayout());

         GridBagConstraints c = new GridBagConstraints();
         c.gridy = 0;  c.insets = new Insets(2,2,2,2);
         c.fill = GridBagConstraints.HORIZONTAL;

         add(new JLabel("Label 000"),c);
         add(new JTextField("Field 0"),c);

         ++c.gridy;
         c.insets = new Insets(20,2,2,2);
         l1 = new JLabel("Label 1");
         add(l1,c);
         tf1 = new JTextField("Field 00001");
         add(tf1,c);

         ++c.gridy;
         c.insets = new Insets(2,2,2,2);
         l2 = new JLabel("Label 2");
         add(l2,c);
         tf2 = new JTextField("Field 2");
         add(tf2,c);

         setBorder(new MyTitledBorder(
          BorderFactory.createLineBorder(Color.BLACK,2),"Title"));
     }

     class MyTitledBorder extends TitledBorder {
         Rectangle rv;

         public MyTitledBorder(Border border, String title) {
             super(border,title);
         }

         public void paintBorder(Component c, Graphics g, int x, int y,
          int width, int height) {
             rv = l1.getBounds();
             rv.add(tf1.getBounds());
             rv.add(l2.getBounds());
             rv.add(tf2.getBounds());
             rv.grow(10,10);

             super.paintBorder(c,g,(int)rv.getX(),(int)rv.getY()-10,
              (int)rv.getWidth(),(int)rv.getHeight()+10);
         }
     }

     public static void main(String[] args) {
         EventQueue.invokeLater(new Runnable() {
             public void run() {
                 JFrame f = new JFrame();
