Well for glass you have to have it as two planes (glass has a front and back. a poligon is infinitately thin so it will look deferent than something with thickness). Glass is white, not blue. make it almost completely transparent with a reflection around .15 and an index of refraction of 1.33. You would want to use an HDRI map for proper lighting. The glare is actually the reflection of the light coming through the window. It can be faked with an image plane with illuminocity. For the numbers I would use two planes again but the first one should be black with trasparency on all the blocks that would make all the numbers and the decimal pionts. It will probably look like something like 888.88 . The second plane under the first will have the blocks lit up to make the numbers.
