I want to start a botnet

I want to start a botnet, but I only know PHP and JS. Is it possible to write a botnet in either of those?

I want to have them work as proxy servers, spam bots, and run metasploit to make new bots. Should I just ship the PHP interpreter with the net? Or perhaps I should have my network run in the browser as JS....

Maybe one of you guys can right my botnet for me?

This is a website that shows how to make a botnet with only PHP by exploiting a new vulnerability in the remote connection protocol of Windows 8.
