First of all, I hate you, macs suck and Steve Jobs is the antichrist!!!!
umm yeah, Virtual machines. They allow you to install other operating systems on current systems.
a good free one is Virtual Box. just use osx86 disks.
and if your PC is recent enough you can install osx86 directly without the virtual machine, because mac is just unix with a mac shell.
parallels. but dont try installing complicated drivers like for HP multifunctions, or intricate webcam software. wont do it. you have to use basic drivers, and configuration is finicky
You can install the new mac os on your windows pc if you have a newish pentium chip.
There is a cracked and hacked version floating around on file share sites
