Does it have to be Python? Our lab has developed a 3D mesh processing tool / framework called OpenFlipper: http://www.openflipper.org/
Would be nice to have Python bindings, though... :)

This /can/ become arbitrarily complex, but you can start out simple. Getting efficient might be a problem.

They do. I wrote a minimal 3D viewer using both: https://github.com/root42/PyGLWidget
It gives you a PyQt based window and a PyOpenGL context. Zoom, translate and rotate via mouse are already implemented. Nothing more, nothing less. I use the widget for small programs where I want to render some simple stuff.
