Need some help with graphics

I want to create candies for a game with the finish like in Candy Crush. I have looked up tutorials on Photoshop but none of them give that 3d look and the glossy finish of the CC candies. What is the best way to achieve this finish? Should I use a modeling program and then bring it into Photoshop? I would appreciate much some direction here.

Thanks,
Syed
