There's a couple threads for NTers who make music.
Also, whenever you decided to get a DAW, go for a small MIDI keyboard, that way you can control any virtual synthesizers.
Like dude up there said, it's more a journey than anything, you're not gonna learn over night and there are times it's gonna be frustrating, but it'll start to click eventually.
There's a bunch of resources on YT.
Major DAWS you should look into "acquiring" : Ableton, Logic, Reason, FL Studio, Sonar, Cubase
I personally use Ableton, I've been going at this for about 2 years now, and I'm still not at a point where I like to share my music.
