IF you have any prior skill on guitar, probably banjo. If you have any prior skill on piano, probably accordion. If you have no prior experience with either, either the banjo or the accordion depending on what you want to sound like and where you want to play. The banjo is the simplest of the three.

Playing any of them well is still gonna be an interesting avocation for years.

As for learning from scratching, that's Spaw's department.
