I'm sorry - but my next question, is why?  What good is it?

What it really appears you want to do is intercept as well as send events for 
the X11 server.  This may, or may not be, within the scope of GTK - I cannot 
say because I would never have cause for doing this since use GTK purely to 
produce front ends to my programs.

I know X11 can do what you want, but programming in X is seriously not fun 
which is why we have GTK, QT, KDE, Motiff, and a few dozen more API's - so 
you don't have to deal with the nightmare of X11.

P.S. if anybody writes back to tell me how dead wrong I am about X11, please 
do it by writing the shortest program you can that prints "hello world" on 
the screen with a seperate button to exit the program.
