First of all, you can remove you fist from your shift key.
Making an Add-On is a lot harder than you're thinking it is.
You've got to either be able to Model or to use Torquescript, or both.
Unless you've got even the slightest idea about either, you're not going to be getting anywhere fast about making Add-Ons.
I suggest reading through some scripts of Add-Ons, to sort of see how scripting works. And for Modelling, you're kind of on your own for that one, Tutorials will help, and perhaps you could get some help from other Add-on makers, if you ask nicely.
I don't make Add-Ons or anything myself, so don't ask me. And if anything is wrong with what I've just said, someone feel free to correct me on it.
