Re: pushpool Frontend for bitcoin opensource can any body point me in the direction
There are several opensource frontends on the forum just search a little bit 
Here the one I usually use: https://bitcointalk.org/index.php?topic=13164.0
Is open source and not difficult to alter (believe me I fixed a couple of things myself hehe)
About the reward system, what exactly do you want to do? With a little bit more of information I can try to help you
Hope this helps you! I will be around in case you want to ask me something hehe
