It's no harder than learning how to flatpick. It'll seem impossible at first, just the same as when you tried changing from a G to a C chord the first time, but give it a few hours, and you'll get a pattern down. I would suggest learning how to play "correctly", focus on proper form. There are tons of youtube videos to help get started. This is the song that I personally learned first... link below.

The right hand technique seems hard, but it's a very regular thumb finger pinch, thumb finger thumb finger pattern. The harder stuff to me was trying to break that back and forward pattern. I still haven't really mastered it, fingestyle isn't my forte, but hopefully soon I'll have a lot more time to play and get back into it. For now I'm just focusing on getting better at strumming and pick accuracy. "Let hand is what you know, right hand is your personality"
BTW I also use these picks ... they work best if you bend them slightly to accommodate the curve of your finger, so the side of the pick doesn't scratch the coil of the strings.
