Yes there does exists such a beast; look at PDCurses (aka
XCurses); http://pdcurses.sf.net

This library enables you to compile and link your application
against libXCurses.so and have the application come up as a
native X11 application (not GTK, or Qt, but native X11, so it
doesn't look particulary pretty). It gives control over fonts,
colors etc via normal X11 resources.

You need to add one line of code to your application so the
X11 application shuts down cleanly. This is explained in the

One other consideration is that if you use the low-level
termcap/terminfo function calls, then these are not supported
by XCurses.

Cheers, Mark.
