Learn Lua, Make Slime Basketball

I've heard that Lua is pretty easy to learn and I love playing slime basketball with my brother. Since I've seen that slime volleyball has been made for PSP with lua, although I do get an error when I try to run it (if anyone could send me a working version that would be great), I figured that the same could be done with slime basketball. Having almost no knowledge of coding aside from writing a few very basic programs like a hello world, how long would it take for me to make a slime basketball program on the PSP using lua? Could I do it in only a couple of weeks?
