"Complicated"? I've never heard that word associated with Macs before! Expensive, yes but complicated,no!
As has been previously stated, to run Windows software like George, you need to have a program such as Parallels or VMWare. I have three Macs and use Parallels on all of them just to run a single Windows program! I've never had any problems with my setup, touch wood.
Nothing is difficult to do so long as you read the instructions.
