Answer: Yes, to some extent.

The following sends a Frame to the top (above all other windows).

   Frame f = new Frame();
   f.setSize(100,100);
   f.setVisible(true);
   f.front();

And the following sends a Frame to the bottom.

   Frame f = new Frame();
   f.setSize(100,100);
   f.setVisible(true);
   f.back();
