Have you tried putting her in big girl underwear? I found that with my son, the diapers are too absorbant and he couldn't feel being wet - it didn't bother him. He's a big fan of the status quo and everything has to be his idea. So i let him pick out his underwear and told him to keep "Lightning McQueen" dry and that he didnt' like to get messy. So of course we had accidents the first day but he finally knew what it was like to feel wet and he did NOT like it. There were accidents and i did ask him about every hour or so if he needed to go. It took a few days, but we've been diaper free (except for bedtime) for several months.
Good luck! just encourage her and let her come to the potty instead of the potty coming at her
