Landing either way is not realistic. Even with no wind airports have a designated runway open. For example a straight North and South "runway" has runway 0 and runway 18, and only one will be open at any given time regardless of windspeed.

If an airport is uncontrolled, planes can land in either direction. Whether the pilots choose to do so is a different matter.

At airports with towers, the controllers can allow landings in either direction. That they usually don't is more of a function of existing traffic.
