I think it's just a ton of work that wouldn't benefit that many
people. If you're using curses on Windows, what are the chances
you end up needing some other part of cygwin for the same
program?

There's a curses emulator written for python called wcurses, that
might provide enough functionality to allow a Windows
implementation of your Python curses program.

It doesn't actually use the windows console, however.

You could write your own little console interface, tailored to
your needs, which is implemented using curses on Unix, and the
effbot's 'console' on Windows.
