Hi Cris,

I'm just the opposite of you (knowing quite well Tk/Tkinter, but nothing 
about X primitives), but I saw once in the comp.lang.tcl newsgroup that you 
could use the equivalent of the winfo_id method on Tkinter widgets to get 
the internal X11 window id, that you should be able to use at the X11 
level. You'll find more info in the Tk manuals, e.g. at 
http://dev.scriptics.com/man/tcl8.3/TkCmd/winfo.htm

I don't know however if it can be of any help for you...
