Knitting is not hard to learn at all. My mom taught me when I was about 8. Once you get the basic knit and purl stitches down, you're good to go - everything else (increases, decreases, cabling, etc.) is just variations.
I can't help you with the quilting, though. I gather it requires a lot of patience, and I'm just not that patient.
I'll join that crochet class...
