I have two 40 gal Betta tanks, that also house 8-10 Platys.. ;) They live quite well together..
Make sure that you have somewhere for them to hide (e.g rocks or driftwood) and add some (fake or real) plants for cover..
Try to avoid getting all male Platys, especially in a smaller tank as they may have territorial battles to see who is the strongest / Alpha Male, so I would suggest one male and two or three females.. If you dont want them to breed, then just get 3 females, although if you do breed them, your Betta will help keep the population down.. ;)
