Ideas For A Small Goldfish Pond?

I just posted a question about a giant flower pot as a water garden on the front porch, but I also want to build one in the back yard so I can enjoy it from my bedroom window while I’m working at my desk.
The problem is, that it has to be semi-temporary. I plan on moving out in a few years, and no one will be here to maintain it and enjoy it. I can do a preformed pond, but I don’t know if I want to bury it or keep it above ground. I just can’t figure out how to “integrate it” into the land around the back yard, since its just a big open yard. Since I’ll be leaving, I don’t want to spend a lot of time adding rocks and plants around it, so it will basically be a water hole (with plants IN the pond) in the yard.
Any suggestions? Should I just stick with the front porch idea and maybe get an aquarium for my room?
