The "Designer" allows you to create a definition of a screen ( it's a
xml file which describes the fields, the positions, the triggers that 
will be executed when different events occur etc).  This file is
latter used by GNUe-Forms for displaying the form and allowing the user
to manipulate the data.
Depending on how you run the GNUe-Forms, the same form (the same xml 
file) can be run without modifications in text-mode (curses),  or in a
graphical environment (by using wxPython or qt or gtk).

As far as I know, the ncurses mode is currently not usable because it is
being translated from the pdcurses module to the curses module which
comes with python by default. The gnue developers surely know more
on the current status of the ncurses-UI and maybe someone else is able
to give us more details about this.
