Riggs, I would suggest doing a Google search on water gardening. If you know what zone you're in (depending on where you are, you may be in a zone 3 or 4), you might add that in your search.
I don't know a lot about water gardens, but I know waterlilies are pretty easy to grow. There are also types of water grasses that are pretty novice-friendly. If you choose some more delicate plants, you may have to over-winter them inside.
You will also want to look into some kind of mosquito defense. If you're not planning on having fish in your pond, you will want to find some kind of the bacterial discs that feed on the mosquito larvae. If you are planning on keeping fish, you will need to find a means for over-wintering them, as well.
You might look for water gardening books at your local library, for more information.
