Most Mac users that want to run windows either set up a bootcamp partition to boot into windows... or use virtual machines (VM) software. The best VM software out right now is either VMware Fusion or Parallels Desktop. You will be pleased with the performance of any of those if your MBP is the 4gb model. If it's the 2gb, I would suggest bootcamp, because then you are not splitting the laptop's resources between the two operating systems.
