HawkEye ShellInit may be worth looking at. It will allow the user to reverse-apportion a section of the screen. I used it in XP to create a 72 pixel band at the bottom of the screen for a RainMeter skin. My desktop resolution automatically adjusted to 1920x1008 and 1920x1128.
You could use it to create space on either side of the screen for your gadgets.
Maybe. I haven't run it in 7.
