If you girlfriend has an account that has been expanded up to Cataclysm, then yes.
If not, no - by itself it is an expansion and needs the full game and previous expansions on the account.
That said, I think there are bundle deals at the Blizzard store for the initial game and all the expansions.
If she doesn't have an account yet, it could be a great idea to look at the Recruit-A-Friend thing too :)

If you buy MoP at a retail store you can give her a copy but, unless it's recently changed, you cannot currently gift the digital copy of MoP. You can only buy the digital copy for your own account.
Edit: Ignore what I posted, they have started to allow gifting digital MoP so you should be fine.
