Better yet, take a look here:

http://www.acoustics.washington.edu/~towler/

(the trailing slash is *required*)

download the directInput.dlm package which is the successor to winInput.dlm
referenced above by Pavel. This dlm is based on directX, is windows only,
and provides an interface to poll keyboard, joystick and mouse states. I
say poll, you still need to run this in a timer loop. It doesn't buffer
input either so the event loop needs to be relatively quick. Usually this
isn't a problem. I provide a simple example.

Also, 5.6 has some new keyboard events for draw widgets which may or may not
work for you.
