Is it possible to create a battlenet account without any blizzard games?

i want to play starcraft 2 beta but it says i need a battlenet acocunt. I have no blizzard games. Can i still create an account or do i have to buy a blizzard game to activate a account. By the way i have a beta key for sc2.|||you can simply register an account under your email then add the beta key under manage games. once you have you can download SC2 Beta and play. You dont need any Blizzard games to create an account.
