You would need a whole lot more than just a root window handle to
write a WM with GDK. 

GDK is an abstraction layer over multiple windowing systems - not all
those systems even have a window manager concept, and they don't all
have a display or a root window. So if you want to use
windowing-system-specific features, you have to write
windowing-system-specific code.

Basically it's impossible to write a window manager with GDK, at least
without using gdk/gdkx.h to access X-specific details.
