Put simply: no.

There are workarounds to getting the entire OS running, but nothing for individual apps.

Of course, plenty of options to do it the other way around

But I'm sure the resident Macaholics will be here to tell you how aweomse the mac is, and how you can buy one on Ebay for $3 and iEnhance your iLife

I suggest emailing Gina at Lifehacker.com and asking if they know of an alternative for the PC, there is almost always a PC version of a Mac app out there somewhere.
