How did you make it? i want to try making an mmorpg too.
And does it take a while?

You need to know some programming skills, like C++ or C

Do you know if a specific program was used?

Man.. If You don't even know what C++ is, stop thinking about making games, it's extremely hard and need very big amount of time.
You can search for some C++ tutorials if You are really interested in programming.

I already know what c++ is. I just need a good free c++ compiler and learn how to do it.

Dev C++ <- this is free complier + editor but I'm not shure if it is in English or only in Polish, you need to check this

For the most programming work I also use dev C++... it isnt a really good development system...but it works
and It is also conserved in many other languages....But it is a hard way get skills for programming an mmorpg...but it is possible
