Try the book called "Potty Training in a Day". It really worked for my first son. I then used the techniques from the book and added a bribery bowl for my second. Both learned in less than a day and NO ACCIDENTS by 2 and 2 1/2.
Now one of the biggest things I learned with the potty training is to get them to do it on their own accord. No asking if they have to go, no pushing them and getting frustrated. When I added the bribery bowl, I filled a huge bowl with things my second boy LOVED and let him dig through it and adore the items. I then took it away and told him he could pick out one toy every time he used the toilet. He screamed and cried and carried on. In the meantime I kept giving him tons to drink (things I would normally never give him, e.g., soda, Koo-aid, etc.) That way he had to pee every 30 minutes or so. He would run up and go then run to the bribery bowl pick a toy, play with it, then flip out that he wanted another. This went on ALL day, but it worked. By day two, it was set and he just went potty or poo poo then went to the bowl. No accidents, no crying.
It is the hardest thing to do but you will find what works for your daughter. Just start with the book and then adjust for her personality. The worst is having to pressure and ask every 10 minutes if she has to go. You both get frustrated.
Good luck!
