I think faucetpod may work, i have seen some tutorial from a russian guy about hosting faucet in blogspot with faucetpod, it should also work with wordpress try it.
This one is easy I just get the code and embed it on on eof my page and it will show up but the popular one it seems is faucetbox they have a long list of faucets that are using their script,
I might try both of them and see who can give me a good results or better i might tried them both and see how good their services is they seems to offer free services
