The software part seems manageable, but I've been intimidated by the hardware component.

The hardest part would be mounting the electric motors to the windows. I don't know what type of windows you have, but if they are single pane windows, a linear actuator will do the trick. Mounting a linear actuator is very simple, and mostly requires two brackets (one at each end). Other potential issue I can foresee is the window lock. But you could use a strong servo to actuate the mechanism.
One big, big issue about your system would be security. In case of a fire, the system might not allow for windows to be used an escape route. Though this only counts if you live in a one or two story house.
Why don't you take pictures of the windows and shoot them over to my email address? I can help you figure out the hardware side of things. (:
