Why not, what is the "requirement" for an apple OS, is it the filesystem, because im sure you could find something out there to format your HDD into apples file system (whatever it may be, im not sure). Then just set up a partition in NTFS or FAT and install windows.
In the mean time while some crazy 16 year old gets busy with the programming in southern russia, you could always just apply an apple mac skin to windows. Even if it doesnt have the functionality of a mac it will look a darn lot like it!!!!
