If you actually mean JPanel, JDesktopPane and JFrame 
(classes in the J2SE - cannot speak for the ones you 
mentioned), then I will add that I am entirely capable of
adding a JPanel (or many) to a JFrame (JDialog, 
JOptionPane, JWindow, JApplet etc.).

I cannot immediately explain why you are not able to 
do it.  Several possiblilities spring to mind, but it
would probably be considered 'rude' to mention them.

Stop, ..STOP.  Besides hurting my head with the 
constant use of the lower case 'j', I read your entire
paragraphs of 'what you want to do' but still do not
understand what you want to offer the end user.

What amazing ability do you wish to offer the end 
user?  What can this GUI do for them that others 
cannot?

Assuming the application had a group of floating,
undecorated areas contained within a larger GUI 
element.  How do I (as potential user) control these 
elements?

How do I close them, or drag them around to 
rearrange them?  Assuming the areas are opened
and closed by other application logic (buttons, menu 
items, the end of a long running process), that really
only leaves positioning.  Using a group of JInternalFrame
instances does not makes much sense unless the 
user can rearrange the order, or drag them about.

Assuming only one of the undecorated areas needs to
be viewed at a time, a CardLayout or JTabbedPane that flips 
between them, might be better.   Otherwise putting the GUI
Elements in a layout where they can all be viewed, such as a 
GridLayout in a JScrollPane might be best.

All this might occur within a JFrame or JWindow or JApplet..
as most appropriate, but I cannot understand the use of a 
JDesktopPane with undecorated GUI elements floating inside 
it.

>I want ..

Yes yes.  'You want', 'you need'.. tell us what the user
is supposed to get on-screen (on terms of what it looks
like and how it works) and we might be able to assist
further.
