Is it really difficult to learn how to play the accordion?

I've been playing the accordion for only a few months, and it's really simple. The hardest part is coordination. In most instruments, you do two things at once, with the Accordion, you're doing three things: Melody(on the right hand, with the piano) your bass patterns(done with the left hand with the buttons) and squeezing the bellows. The reed buttons(on the left) are amazingly easy to learn. Top two rows are your root notes(ABCDEFG), where the buttons directly below, in the same column, provide your chords. Just watch a video on it on Youtube. It's alot more easy to understand it by watching, not reading. Then that's it! Learn simple songs on the piano, and teach yourself the bass chords to go with it. I taught myself alot of Flogging Molly songs by being able to play the accoustic chords on the guitar, but just play the exact same chords on the accordion's bass reeds while playing the melody. It sounds complicated, and is probably the most intimidating instrument I've picked up(I also play the Mandolin and Irish Tin Whistle), but after a few days, I found myself laughing with glee as I figured it out easily

No, it's really quite easy. You can be taught by a professional accordion teacher.....or you can pick up the Palmer-Hughes Accordion Course books (very easy to follow) and teach yourself. Alfred Publishing Co. puts them out.... http://alfredpublishing.com/alfredweb/front/ProductDetail.aspx?itemnum=%20%20%20%20%20%20%20202&pubnum=0
