Be careful when you get ready to remove the glass, loosen the bolts that hold the tracks to the door and be careful removing the window. when I removed my windows to change out my door handles I had to tilt the front side of the window down and very gently thread the window out from the handle side. Be very careful and take your time because you could easily scratch the glass or even worse break it, The reverse process is the same for re installing the window back into the door, remember to properly align the stops and check the window for proper sealing before reattaching door skin and handle. Good luck!!! Take your time and you will be fine.
