Lots of guys buy planes without having a license, but they usually hire pilots.
If you want to fly the thing yourself, you will need to get a PPL, followed by a CPL (plus Multi engine) and IR-ME, then get a type rating for the thing.
I'm not sure if you need a CPL to get a type rating, but you will want a CPL anyway for insurance purposes. You will also have to find a second pilot since it is a two crew aircraft.
