Cutting molding - round

Couple of ways. Using a piloted bit on a prepared piece, or making a template for use with guides. Generally easier in the long run to use the guide and run it on a table. That way you smooth a 1/4 ply template edge and use a flush-cutting bit to smooth the thicker wood.

Assuming you are talking about a reasonable radius and you are talking about only cutting from the surface the easiest way would be to use a radius arm attached to router.

It is possible - I've done it with a CNC router and I've seen curved moldings made on both shaper and special-purpose molding machines.

Would flexible, plastic moulding do the job?

I recently put a french door in an arched opening, and plastic quarter- round worked great to hold the transom lights in place. Granted, it's fake, but at seven feet off the ground, no one will notice.

The hardest part of the job was getting the miters right at the pointy end of the window.
