I think there is (slow) movement towards that.  Certainly it's
possible now (you can add menus to Rgui in Windows, you can do nice
things like Rcmdr using TCL/TK on any platform).   However, designing
a nice GUI is very hard work.

That would be helpful, and the only really difficult part would be the
first part:  getting the user to the right function.  help.search()
sometimes works, but often people ask for the wrong thing.

After that, R knows a lot about the structure of its help files, so it
could display all of the arguments with their defaults and the help
text that corresponds to each argument, as well as the help text for
the rest of the help file.

Probably the main obstacle to getting this is finding someone with the
time and interest to do it.
