There is an issue concerning who calls who. There
is an extended version of Tcl/Tk called Expect,
and a book on same on my shelf called "Exploring
Expect". Expect calls a program and then
exchanges information depending on the last
message from the called program. Whether this is
your ultimate version of Tcl/TK is of course up
to you but that is another and interesting option.

Another option:

Tiny COBOL allowed the calling program to be
COBOL and had a C language interface program to
tcl/tk. In the tinycobol66 release look for examples
tgui01 and tgui02 in the test.code directory.
