Best language to develop a free MMORPG?

I’ve been extremely interested in programming a simple mmorpg. But I don’t want to have to pay for a giant server to support it.

I’d really like to program it so that it is web-based, but don’t know how to make the clients have to run their own servers. Is there a particular language that is known for making client-side server connections to web-based games?

I’m a friggin programming idiot. :open_mouth:
Any advice would be good.

(I was originally thinking about Flash/PHP, but heard Flash doesn’t support client-side servers.)
