Hi Shawn and welcome. There are 3 ways I can think of offhand to make a curved frame out of solid wood. One is to steam the wood and bend it. Next is to take some thin veneers (maybe a 1/16' thick) and glue them and the laminate them around a frame. Last is to laminate wooden blocks together in a way that they angle around so that you can bandsaw or jigsaw the shape you need. The idea with that method is to keep the long grain in the wood running in the same direction as the frame is.
