There some good tutorials on mitering the corners for bindings. Google mitering quilt binding and look for the one that helps you most. Once you get the hang of it, it is so easy you can't remember why you thought it was hard. Practice with some 9 or 10 inch square potholders. That way, even if you mess up several times, you'll still have something useful and you won't feel compelled to rip out any stitches. Potholders are also called "kitchen quilts," if that will make you feel like you are doing the "real" thing.
