Hungarian is even difficult for other Eastern Europeans. I have yet to meet anybody that speaks Hungarian, that is not actually Hungarian.
I'm American, but I can speak Hungarian. The language is like legos. You build words out of little blocks. I love it.
So it can definitely be done (as with any other language), although you need strong motivation and a bit love of the language. But I think there are not many people in the world who has the motivation for learning an obscure language that is only spoken in one Eastern European country.
