After hours chasing down bugs i finally built code to generate windows! I also added a rough 3D prioritization method for the last window drawn (The "Active" window) to this demo. One step closer to my goal!

Are you pushing the windows onto an array?

Not currently. Each window is 9 sprites (8 sprites linked to a 9th "master sprite"); This test was to test a subroutine that could create multiple windows efficiently. I do plan on using an numeric array however to store a list of the master sprites (which affect entire window position and appearance) in the actual system.
