Siding makes it an easier project than if you had brick.
The tricky part is flashing them correctly to prevent window leak.
Just be sure to seal the window correctly. A lot of times glass block windows don't have flanges (you can't screw the window from the outside - you have to screw it in from the frame on the inside) so be sure to use window wrap and flash the window correctly.
