Electrically it's not too crazy. How the switches look might get tricky.
If you mount the switches in the console the door panels can be smoooth.
The switches can be super tiny if relays are used to do the power switching.
2 switches are required, 1 for each window. They are called single pole double pole (SPDT) momentary, center off.
Each switch will control 2 relays. One relay for UP and one relay for DOWN.
See attached schematic for wiring.

If relays are no good you can use a DPDT switch. See Attached schematic.
