Micro Controller software on a pc (pc as a P.I.C)

Zapnologica:
Is there like a linux distro or a program etc, im not sure.

That i can load onto a computer (in my case a thin client) and then use its paralle port as io pins?

Can you clarify? Do you mean a PC (like, a Windows PC)? Or a PIC chip (like, the things Microchip makes)?
