I trimmed out the window with 1/2" x 3/4" x 1/16" thick aluminum stock.

I placed the 3/4" edge out on the wood surface all the way around except for the bottom section. There I reversed the trim and inserted the 3/4" edge into the window ledge due to the design of the window.

Turned out very clean.
