yes!
In general, you don't need a driver's license to operate a vehicle on private property (such as, say, a golf course). You cannot drive a golf cart on the street, because golf carts are not street legal vehicles. If you modified one in such a way as to make it street legal, then yes, you would need a driver's license to drive it on the street.
Whether that's legal depends on your state. In Arizona, for instance, modifying golf carts to be street legal is allowed. Here's an article on that: http://faircompanies.com/news/view/road-midgets-diy-nevs-and-solar-golf-carts/
