[Dragon Ball] Can I build up my ki energy and learn to fly and shoot lasers by learning other martial arts, or do I need karate/kung fu?

Also if it does work with any martial art, is there a difference between how your ki develops depending on the fighting style? Like, can MMA fighters fly more easily than boxers or capoeira fighters?

It has been shown that the characters use of martial arts is just one method of expressing their study and dedication.  At least one character learns to harness ki and levitate solely using meditation.  Likewise Piccolo's primary method of gaining power is meditation as well.

The exact martial art used does not seem to matter, though the various masters and teachers each have their own preferences.

I believe there's a fairly detailed post about it from a week or two ago.
