I am a head start teacher in WI and I think she should maybe check out a head start program in your area, she may not learn to read a book but she will learn enough sight words to understand a story for someone her age. If you are doing this at home, try first to use flash cards with pictures and words as a game to play, she will learn these words and recognize them while trying to read a story and read stories with her and have her follow along while you read, read the same story for 2 weeks at a time and encourage her to say the next line at different points during the story yes, she will memorize it, but she will also be learning the words as she sees you pointing at the words. I have a class of 21 kids ages from 3 - 5 years old and out of them I have only 2 that haven't caught on to this yet but both of them just started in my class in the last month, if you are patient and willing to spend a lot of time on it your child will have some of the basic skills she needs to read in a few months, also while you are reading pick out words and use those in your flash cards. This way she can identify with the words in a story.
As for not being interested in reading, she may need more interesting books to read, try character stories that she may like, such as Dora the Explorer, or other character stories from T.V. she may like. With Dora she would be learning to read in English and be learning a small bit of Spanish also, sometimes this interesting to children also, we try to teach our kids words in other languages here and there also if they are ready to learn that don't just put those words in though unless she gets it in English first!
