You may want to look at discrete window user script for SketchUp Plugin that Mohammad Heidarinejad made, it has window width and height, and number of window height as arguments, along with offset. arguments. It looked very cool but I haven't had a chance to test it out. Looks like while there is wwr argument it currently uses the number of windows vs. the wwr.wwr, but it could be adapted to make a target wwr and it would pick the closest number of windows to hit that.
