I like Picasa's interface. It looks nice and is very easy to use. I agree, however, that it is not ideal for anything but the most basic editing. There are lots of great programs you can look into if you want to do more intensive editing. Lots of people use Elements (might be a good idea if you plan to move up to Photoshop someday). Other people, like dEAR, recommend Paint Shop Pro. I would say to download a few and try them out and see which you like best. I'm sure they are all good programs, the only difference would be which one you find easier to use.
