Drop-in curses to X library
 

I understand the puzzling futility about which I am asking.

Is there a library, free or commercial, that:
-copies the interface of the curses API
-serves as a drop-in replacement for curses
-produces X widgets--Tk, Gtk, anything...

We are attempting to put a quick-and-dirty pretty face on console applications which have been written in curses, beyond putting them in an xterm with a bigger font.

Thanks for any suggestions.

The standard curses implementation on Linux is ncurses

For Tk widgets, use Tk. For gtk widgets, use gtk. Not sure what you're asking here?

The quickest and easiest way to implement X widgets is (IMO) to use Python's Tk module. (Or Python's gtk module).
Python can interface with C code without too much trouble.
