You may want to discuss Tcl/Tk issues on comp.lang.tcl.  There are
much more people with specific Tcl/Tk knowledge there.

Which error?  If Tcl_Init() returns an error, that can be a
configuration error in the Tcl/Tk installation or an error in the
calling sequence.  I remember that it is important to call
Tcl_FindExecutable(), especially on Windows.

There have been significant changes in Tcl/Tk from 8.0 to 8.1 (most
importantly the switch to Unicode), so using a more recent version may
complicate matters.  You may instead want to use the version 8.0.5
from http://sourceforge.net/project/showfiles.php?group_id=10894.
That page has source as well as native Windows Tcl versions.

The native Windows version of Tk has some X11 emulation built-in for
it's own use, so you may want to try to use that first.  If that X11
emulation isn't enough for you, you can compile your own 8.0 Cygwin
Tcl/Tk and run that under Cygwin-XFree86, there is no reason that that
couldn't work.
