PMW+BLT on windows, any chance?

[Giacomo Boffi]

on my linux box i have a small python program that draws some 2-d line
graphs in a window aside a graphical interface to change the problem
data

as you may have guessed from the subject line, the gui widgets are
done with help from PMW [1], and the graps are done by the PMW <->
BLT[2] interface

now i'd like to port the whole mess to windows to give it away to
unix-impaired people, but i cannot find a precompiled BLT for my
window (virtual)box

otoh, even if i find such a rare pearl, every reference i found on
google implies that BLT 2.4z works with tk<8.5 while python 2.7 comes
with tk 8.5

1. is it possible to do what i wish to do?
2. is it worth?
3. if it is impossible or unworty, i'd better rewrite my program to
   use which graphics library?

tia,

[1] Python Mega Widgets is a pure python implementation of complex,
    expandable widgets built on tkinter, i use its input widgets
    because they do data validation
[2] Blt is a library that enhances tcl/tk adding some useful stuff, in
    my case i use the 2-d graph widget
