Getting the desktop (root) window handle is easy -- use
GetDesktopWindow().  What you are trying to do with it
however, is evil.  The window provides all kinds of funky
behind the scenes coordination for its kids (every other
window).  Replacing it (by subclassing I assume) would
likely cause Windows to explode in your face (watch out
for shrapnel from the screen ;).

Even subclassing only the WM_PAINT message (for displaying
the backgound bitmap and wallpaper) is going to be
non-trivial if it can be done at all...
