A GUI can be used in Unix (in fact, several). Most power users don't use the GUI because it can be too limiting. The power of what you can do in Unix is at the command line, not using a GUI to click on buttons. Of course, this could be said about most operating systems; the GUI is there for user convenience but most administrators use the command line for most of their work.
