The day you spent doing this, you could of learnt a programming language and have done this.
I don't think you can learn a programming language in a day.. unless you stick with it 24/7.
But still, I don't know why people want to code and then make RPG's with it when there are engines for you to make them. Coding is not necessary but there is a coding engine in RPG Maker. The only time you would need to code for a game is when the game making program you are using isn't fitting your needs.
