If you want one source then I don't have it but I know Youtube has tons of those. With just a 1 minute search I found this:

It's a complete tutorial the only problem is that there's no voice-over but I know with a deep search you'll find a lot of them. Just search for terms like "
make swedish house mafia style..." "
make music like avicii" "
fl studio swedish house mafia style" or anything. These are just ideas, only you know best as to what you want.
Hope that helps but some music theory always make things much easier. Learn to play at least 1 instrument on the side, even though you don't perfect it just as long as you understand chords and scales then the rest will mostly come naturally as you keep practicing.
