First, have you looked at gdm? It is GTK+ replacement
for xdm which is pretty much complete and functional.

(It is on the GNOME CVS server, and you can find tarballs
 in ftp://ftp.gnome.org/pub/GNOME/sources/)

It isn't possible to have the same GTK+ program disconnect
from an X server and reconnect to a different X server,
if that is what you are trying to do.

I believe what gdm does is separate itself into two
processes - gdm, the daemon, and gdm-greeter, a GTK+
program which handles the user interface.

This also should help make the program secure, by removing
complexity from the portions that need to run as
root.

Destroying the toplevel window will destroy all children.
It won't, however, disconnect you from the X display.
