My main motive was the fact that wpa_gui will not work unless you already
have a working wpa_supplicant.conf & wpa_supplicant is running.
(My script was partly inspired by how hard it is to figure out what goes
in wpa_supplicant.conf if you've never used wpa_supplicant before.)
It also has to do with Qt4 vs. dialog: one drags in one of the largest
GUI toolkits around, and the other is a couple hundred kilobytes,
runs in text mode, and only depends on a single library that's basically
guaranteed to be installed and implements a POSIX API, with an installed
size in the half megabyte range.
(In case you're wondering about the "POSIX API" part, curses is part of
POSIX; dialog only needs ncurses.)

For what it's worth, my script also works with whiptail, although --
contrary to the whiptail docs -- whiptail ends up using many times
the space on i386, between libslang, libnewt, and libpopt, besides
being buggy. In theory, it will also work with Xdialog if you have it.

I don't recall seeing any signs of such a limitation when I used wicd
for connecting to wireless at home and at college...
That said, when I tried it was fond of spawning lots of wpa_supplicant
processes.
