Question: is polish a hard language to learn? 

Answer: I don't know -- but very young Polish children seem to be able to do it. All kidding aside, it depends on how you do it. If you have an opportunity to associate with Polish people and put to use what you are learning, it will be much easier. Any language is hard to learn if you learn it in isolation and only use it in text book training.
