Language / learning Polish using American phonics [24]

I am the mother-in law of a wonderful polish woman. Her parents are coming to the USA in June and I would love to be able to speak to them. Is there a Polish course on the computer, a cd or something that teaches Polish using American phonics? I found one course on the computer but it only gave 5 important phrases like " Good morning" or "how are you". If anyone can help me, I would appreciate this so much.
