Does anyone crafty out there know how to make soap without using any fat products? - pure olive oil soap

I wonder if you can make soap with a strong aroma and a natural base of pure olive oil instead of fat. Has anyone any suggestions on how you can do to maintain and preserve the freshness and fragrance? How about a scent of mint oatmeal? Or the type of apple? One that smrlls tart apples fresh and cooked when you use the shower? Ideas?
