Ask yourself why your daughter is exhibiting these behaviors. Are her verbal skills not as well-developed as those of her peers? Does she know appropriate ways to get attention from her friends? Is she younger developmentally than the other children in kindergarten? Talk with the school counselor. He may be able to give your daughter some individual time or include her in a small group on good communication skills.
Keep in mind that any kind of behavioral system that you try must be used over a long period of time, and it must be enforced consistently.
