And if you are too impatient for that, just use Tcl/Tk.  Tcl is a basic
scripting language that comes with a basic GUI toolkit.  One that you
can play with *interactively*.  Once you have Tcl/Tk installed (under
Linux it is just a matter of

# Red Hat flavored (RHEL, CentOS, Scientific Linux, Fedora)
yum install tcl tk
# Debian flavored (Debian, Ubuntu, Mint, etc.)
apt-get install tcl tk

), you can do this ('%'=shell prompt):

% wish
pack [entry .e]

and presto, a text input box.

A slightly more exciting example:

% wish
pack [entry .e] -side left
pack [buttom .b \
	-text "Hit me" \
	-command {puts "You entered: '[.e cget -text]'"}] -side right

The packages *should* come with man pages.  Also: visit
http://wiki.tcl.tk/ for lots of fun stuff.
