There is nothing in GPL to stop a commercial GUI for R. Have a look at what Apple do. They have a complete commercial GUI and numerous applications built on a an almost completely GPL'ed operating system. There are loads of shareware GUIs which drive GPL utilities. Most obviously there are plenty of commercial apps which run on GNU Linux.If the GPL were not so tight on this point, someone could commercialize a GUI for R without having to offer their source code under the GPL.
