The point of GDK is to abstract windowing system calls, but that only
makes sense when the concept actually makes sense cross platform...
things like drawing a line or maximizing a window generally 
do make sense.

As I understand it, what you want to do is, given the XID of the
nedit window, you want to send it a KeyPress event. Windows on Win32
don't have XID's, of course, and while there might be a somewhat
similar concept of sending a key-pressed message to a toplevel
window handle, the details are going to be quite different. 

Presumably you got the XID of the nedit window in some X-specific
way. Once you are doing X specific things, there is no particular
virtue in turning around and trying to do everything else through
GDK.
