Has she tried using a physical seam guide on her sewing machine? I create one with moleskin to build up an edge. This makes sewing strips together with an accurate seam pretty easy. The strips can be slid together and (provided there is some space in front of the machine) held down with a hand.
She might want to start out with a "cheater" top. This is a fabric panel that is printed to look like a pieced top. You layer it for machine quilting. If she has a newer machine, it's really easy to machine quilt using a serpentine stitch (instead of stitch-in-the-ditch) and the results are very nice. Here is a link to a baby quilt kit that uses a "cheater" panel:

If she wants to get fancy using free-motion machine embroidery on the quilt top, Ann Fahl has some good books and a video out on how to do that.
