in my case non-Tk GUI is not a standalone independent program, but rather
specially written for this case.
If I write GUI using Tk, I prefer using it in a most portable way,
i.e. without non-portable additions like external inclusions.
But here I am tempting to do several different kinds of things.
<bl>
1. extend Tk GUI functionality by creating non-Tk widget with
a native to current platform widget, for example Borland VCL or CLX,
for example, data-aware widgets
2. opposite case (after I'll understand underlying mechanics)
to enrich my other Win32 GUI application with a powerfullest Text widget
I ever saw, as well as other well-done Tk widgets.
3. everything else I've forgot to mention :)
