How do I get a dialog box to reappear?

Question

I'm trying to write an application where
1. There is an opening frame. The user can click a 'start' button which
opens the first of a series of dialog boxes.
2 Each of these dialog boxes has a user input field and buttons 'next' 'back' and 'cancel' , to step forward/backward through user input , or to cancel & return to the opening frame.
3. As each dialog box opens up , the preceeding one should be hid.
4. If the user clicks 'back' , the current box should close and the
preceeding one should reopen.
Straightforward enough and I've got this working at the start of the progam
for the transition between the opening frame and the first dialog box, by
doing this:
in the opening frame...
//start button..
this.setVisible(false);
Dialog001 d001 = new Dialog001(this,"",true);
d001.setVisible(true);;
and in the code in the dialog box d001, for the '<< back' button..
void button1_actionPerformed(ActionEvent e) {
dispose();
super.getOwner().setVisible(true);
*********** so far so good : everything works OK **************
The problem is when I repeat this in the second dialog box , the
first dialog box doesn't reappear.
I have looked in the books and tries various things, but no good
so far
How do I get the previous dialog box to reappear?
Also, how will the 'cancel' button work in the second (and subsequent)
dialog boxes (instead of the preceeding dialog box reappearing, the
original opening frame should reappear) ?
Thanks in advance

How is this: (you can change it from Swing to AWT.)
setVisible(false);
int index = 0;     
Vector v  = new Vector();
dialog d;
while (index != -1)
     if (index == v.size())
           v.add(new dialog(this,index));
          d = (dialog)v.get(index);
     else
          d = (dialog)v.get(index);
              d.setVisible(true);     
     index = d.ret;
     setVisible(true);
public class dialog extends JDialog
     JButton next = new JButton("next");
     JButton back = new JButton("back");
     JButton canc = new JButton("cancel");
     int     me;
     int     ret;
public dialog(JFrame f,int i)
     super(f,""+i,true);
     me = i;
     getContentPane().setLayout(new GridLayout(4,0));     
     getContentPane().add(next); 
     getContentPane().add(back);
     getContentPane().add(canc);
     next.addActionListener(new ActionListener()
     {     public void actionPerformed( ActionEvent e )
          {     ret = me+1;      
               setVisible(false);     
     back.addActionListener(new ActionListener()
     {     public void actionPerformed( ActionEvent e )
          {     ret = me-1;
               setVisible(false);          
     canc.addActionListener(new ActionListener()
     {     public void actionPerformed( ActionEvent e )
          {     ret = -1;
               setVisible(false);          
     getContentPane().add(new TextField("abced"));
     setBounds(100,100,100,150);
     setVisible(true);
