Why don't you just build a swimming pool and put fish in it? Same difference.
Deb In addition to what has been said, also check the ph level of the well water to make sure it is not acid or alkaline. Because it has come out of the ground, it can be a lot different to rain or river water. It also won't have much oxygen in it, so you might need an aerator or something to churn the water surface. Finally check the water temperature and make sure in the summer, the temperature doesn't make the water too hot to harm the fish.
Cement is fine, but you will need a coater. Do not just put cement in and fill the pond. Ask your local pool/pet store about this.. There is a paint you can prime cement with to make sure the cement does not get logged
