This is what I did with my children. I took them shopping for underwear and let them pick whatever they wanted. Then we went and bought stickers, again whatever they wanted. When we got home I printed a calendar and we hung that in the bathroom and we put the stickers in the bath room. Everytime they went potty they got to put a sticker on the calendar. After "X" amount of stickers they got a treat, either we would go for ice cream or I would make their favorite dinner.
Make it something that is exciting and fun. Don't push to hard because if she is not ready she isn't going to do it and since there are very few things she can control, this is one of them. So she will control it if she feels to much pressure.
