In case there isn't, it's not completely trivial in Windows NT based
operating systems. (any flavor NT, 2000, XP, Vista or 7)

For easy programmability I'd suggest a USB microcontroller and using
libusb for the host software. There's a lualibusb binding at
luaforge.net, which should make it easy to access the device.

I personally like the cheap Olimex LPC-P1343 board:

Here's some sample source for a project I do in a workshop with the
above board:
