title: Is it possible to create several subwindows in the main window area in JavaFX2?
body: <p>I think the following screenshot from mIRC will help you to understand my problem.</p>

  <p>I have a main Stage (1), and in some Pane (or any other container) (2), I would like to add several subwindows (3) in such way so <strong>they cannot be moved outside the owning window</strong> and they <strong>are not visible/selectable in the OS taskbar</strong>.</p>
  
  <p>Is there a way to do it in JavaFX 2.2?
  If not with windows (separate Stages), is it doable with any other movable containers?</p>
