It is possible to do that, either when creating the widget in Gtk,
or even after creation using XReparentWindow. Howover, more natural
and probably also

more to your friend's customers liking, would be to extend Tcl/Tk with
some glue code that links to the widget he wants. Tcl/Tk was *made*
for incorporating C extensions (a fact most people forget).

There is a lot of documentation how to do that; a quick search turns
up for example the "Engineering Guide for the Tcl core implementation
and C-level extensions." by John Ousterhout himself, on 

http://tcl.activestate.com/doc/
