NURBS are not actually Bezier curves, AFAIK, they are a
superset of some kind (which means they're probably better
to use, but harder to implement).

Not a specific recommendation, and I don't know if it's
any more comprehensible, but you will find that Skencil also
implements Bezier curves (in 2D).  Skencil is mostly in
Python, but uses a lot of C, so I don't know if it handles
beziers in Python or C (I'm still learning my way around the
code, myself).

Inkscape, of course, does too, but in C.

Or NURBS, yeah, probably.
