Python TUI that will work on DOS/Windows and Unix/Linux

[James Harris]

Am looking for a TUI (textual user interface) mechanism to allow a Python 
program to create and update a display in text mode. For example, if a 
command prompt was sized 80x25 it would be made up of 80 x 25 = 2000 
characters. The Python program would need to be able to write to any of 
those 2000 characters at any time though in practice the display would 
normally be arranged by dividing it up into non-overlapping rectangular 
regions.

I have seen that there are various libraries: urwid, newt, console, dialog 
etc. But they seem to be either for Unix or for DOS, not for both. I am 
looking for a library that will run under either.

Furthermore, some libraries are complex, providing widgets of all kinds. I 
am looking for something much simpler and the lighter-weight it is the 
better. At least at this stage I pretty much just want to divide the screen 
up into panels.

Input from keyboard would be essential. Input from a mouse would be nice to 
have.

Especially if you have had a similar requirement in the past but even if 
not, is there any cross-platform system you would recommend?
