The power windows could be done pretty easily with a fuse holder with pigtails on it. Remove the power window fuse, then just crimp/solder male blade terminals on each end of the fuse holder, plug one end into a spare BAT plug in the fuse box and the other end into the fused side of the Power Window fuse terminal (the one that does not have power when the fuse is removed and the key is in the ON position) Then just take the removed fuse and put it into the holder.
DO NOT USE A JUMPER WIRE WITHOUT FUSING!!!!! Those windows use a ton of amps and if you have a switch stick or something short out, you will have a fire in short order.
The radio could be done with a toggle switch between the always on B+ wire and ACC wire going to the radio.
