You don't need to be an aquascaper. If you can keep fish you can keep plants. The problem is most LFS mostly sell difficult high light plants and submerged house plants so you come back after a month to buy more. Start with easy low light plants such as Java fern, Anubias, guppy grass, Crypts, Java moss, dwarf hygro, there are many more. Check Craigslist or the local aquarium club, many hobbyists give away cuttings.
