if you don' tfeel you can get the hang of doing one long binding with mitered corners, you can simply add binding to the sides and then the top and bottom individually. you just cut binding (i cut 2 1/2 inches and fold wrong sides together) make the cut at least 1 inch longer than the length of your quilt sides or top or bottom. fold over excess on each end of binding piece, fold together and lay on the top of your quilt, raw edges meeting. sew and flip to teh back and hand stitch down. (some sew by machine also).
many quilts are done this way, so don't fret too much. try it on one quilt top while you read up on doing mitered borders on binding.
