Full-screen Python TKinter or wxPython window, but stay below all windows?

I want to create a full-screen panel that visually blocks access to everything on the screen (desktop, menu, Unity panel, etc. in Ubuntu (11.10)), but remains below the open application windows.

This is mainly in order to make the child a laptop proof. I want the child (4 years old) to have access to some selected applications, i.e. gcompris, a children's game, tux math, etc., but not quite for other applications and settings. Something like a custom desktop bar + launcher without any hacks, without access to files, etc.

I want the panel to contain some buttons that would launch other applications (using subprocess.call), but the panel itself should remain under something that was launched from it, or simplify the task so that it remains under any open full-screen games and each open window (even if the panel is focused).

Python tkinter fullscreen overrideredirect (True) would be ideal (with a password-protected close button), if not for the fact that it does not allow other applications to appear above it, and I'm not sure that you can do this at the bottom of everything.

Any idea how to change this behavior, if possible, or any other tools that would allow me to do this in python or otherwise?
