The only "officially-created" Star Wars language so far is Karen Traviss' Mando'a, but since I hate her and everything she's done to my beloved Mandalorians, we'll not talk about it anymore.
Other than that, I know there are phrases and words for languages like Bocce, Huttese, Ewokese, and probably a few others up on Wookieepedia.
I've never read anything from Wookieepedia, that's just too nerdy.
