Gecko (http://www.geckodrive.com/) makes nice but not too expensive
stepper motor drivers. You still need to determine the wiring
arrangement for the stepper, but there's plenty of info on the Web on
how to use a meter to separate out the windings in the typeical bipolar
and unipolar stepper. You will need to scrounge up a power supply, but
those are easy to find surplus for cheap. A 500 mA wall wart will
probably work, depending on the current demands of your motor.
I don't know if they have any C/C++ programming example, but basically
all you need is access to the parallel port. On later versions of
Windows you'll probably need a driver to allow access, as Windows takes
over the hardware. Jan Axelson has a vbery good book on parallel port
interfacing, and her page includes links to examples:
