You can take a normal window and slice it down the middle. Now rotate one half 90% and slide it over to the other part. Line up the outer most points that represent the glass facing the outside (or inside, you pick). Now weld all those outside point. Next, select the inside points, section by section, on both halves of the inside elements and 'collapse' them and then weld them. You'll now have a corner window. Lastly, save that window in a folder of assets so you can use it again.
You should be able to make the window in about 10-minutes or less.
