X11 gui programming - suggestions please

I am working on a hobbyist project to generate a coded text file based on
user input.

I am using C++, and MVC design pattern(s). Have decided it will be licensed GPL v3.

For the GUI (view the user will interact with) I am researching gtk,
curses, and such, but never have used any of them before on a project.

Hoping my fellow Debian LJers (might x-post to the LJ linux grp, too) might have ideas/suggestions based on your
experience doing GUI programming.

I dont' think I will need to draw graphics or images. At this stage I
expect my GUI would just need to view/display/intake keyboard text.

Btw, I asked my SGVLUGers, and have the following as suggestions so far (in no particular order):

ncurses
qt
gtk + glade
fltk
jx

Thanks
Robert
