Well it's the same problem you're trying to solve today.  You've got a
text console with a cursor you can move around and print out text.
Besides with any modern operation system you can't write directly to the
screen anyway, like we used to back in the DOS days when we poked
directly into video memory.

A toolkit (that's old, arguably), that might help you is TVision, a port
of the old Turbo Vision library that formed the foundation for Borland's
old DOS IDEs back in the day (check wikipedia).  And it looked quite
beautiful back then, actually.  There is a Python binding for it here:

https://pypi.python.org/pypi/PyTVision

The original C++ is here:
http://tvision.sourceforge.net/

TVision does run on DOS, Windows console, and of course Unix, though
you'd need the appropriate shared library.

Or you could write your own, based on top of something like curses.
