hello L2 community!

I've always wanted to make/create my own server, I have a lot of creative ideas to make a pretty nice and unique server, but the question is.... I don't have any knowledge of C++, java language or anything like that. Would it be to difficult to fix/investigate any bugs that appear as time goes on, would it be to difficult to mod the game as I want ( EX: put custom stuff) (Change npc loc) etc...
maybe its just a dream I cant achieve because of poor java knowledge?

please let me know what you think! ^^
