Rip down each shelf with the table saw to mimic the width of the jamb legs, and router each end of the shelf for that smooth, polished look.
For the stained-glass area, add a stopper, using 1/4 round cut to size of window frame. Cut each individual piece using a chop saw.
When all four pieces are installed, carefully insert the stained glass into the area. Attach the other side of the stopper on the reverse side of the stained glass to keep it in place.
Remove all the shelves to prime and paint your desired color.
Add some trim around the border of the window, and re-install the shelves.
