Look for some top down baby sweaters. They're cardigans that can be knit without seams, except for the sleeves, which are pretty short. You can chain a loop of yarn for a button loop instead of a hole. Look at knittingpatterncentral.com, thedailyknitter.com and there's a free one at http://www.knittingpureandsimple.com/babycardi.html
I just did my first sweatern and posted it. I used a pattern y Knitting Pure & Simple. It was basically all in one piece except where you go back and pick up stitches for the sleeves. But if I can do it you can!
And I just picked up a baby sweater pattern today at my LYS and it is called 1,2,3 Top Down #609 by Cabin Fever and looks pretty simple.
