you will need you PWM signal to be fed via a Hbridge as it has to be dual polarity for the voltage multiplier to work

You don't need an h-bridge, a half bridge will do.

What voltage do you need? Using a flyback transformer is normally the best way to go.

I'd be interested in see the total design.  I have a coil gun project as well.  I'd be interested in seeing your coil geometry and your efficiency.
