Bot for Facebook Like and Google + Vote

I need a bot that will log into more Facebook accounts simultaneously and perform a simple action - click Like button on few sites that I will import into program. The bot must support hundreds of FB accounts without crashing. The difficulty is the multithreading task without interfering accounts between them and memory management so the program will not crash. I also need bot (it can be the same or separate) that would do log in to Google account and Google +1 vote in my web sites, Google +1 vote in my links and Google +1 vote in Google search. Program has to run on my windows 7 machine and support captchas and proxies.
