The better your crust, the better the pizza, but heck, even using pre-made Boboli pizza crust can yield a good tasting home-made pizza.
Although, I'd certainly recommend getting some dough from your local grocery store and throwing it yourself... it's a skill that's surprisingly satisfying to learn and to get good at, plus it makes the entire experience a ton more fun and enjoyable (and it'll impress guests as well)!
Pizza is very easy to make, and can be a lot of fun!
