Running of MAC Software on a PC

Does anyone know if it is possible to run a MAC Program on a PC. I don’t know much about MAC & I have a friend who has a daughter with a Learning Disability. He purchased a special screen (Touch Type) to allow her to use the Computer (It is the only stimulis she reactes to). Unfortunately a software package that he purchased for her (through her therapist) is only in MAC format.

He contacted the company & told him they had not considered converting it to PC format. He really can’t afford to purchase a new machine. Can anyone help me or recommend a point of resource that I can give to him.

Thank You in Advance
