Try Java-Gaming forums instead.
I hope you know how to program.

I made my first game for a school project. Took about 2 weeks. Its some kind of space invader. The enemy is controlled by a Bot which is on a TCP server. Was a requirement lol.
I only used LWJGL for the Audio. Made the rest from scratch.
Its doable but do the OpenGL tutorials for LWJGL first. RTS is not the easiest to start with tho.
