I have to disagree with you.  What you say might be true about *bad*
GUIs, but I find nothing more frustrating than the lack of programming
support in R.

What's a nice GUI for programming?

You should be able to edit code, and have R parse the code that you
are editing.  The current disconnect between the source file and what
is in R makes debugging really painful.  I'd like to single step
through a function, and when I spot the error, *edit it right there*.
I'd like to be able to use the mouse to find the contents of a
variable as I'm single stepping.  I'd like code-completion to be
possible in the editor, and help hints based on what I'm typing.

All of these things have existed for years in IDEs (i.e. programming
GUIs), but most are not in R's GUIs.
That's one sort of GUI that R could have, but it's not the only one,
and it's not the one that I'd use.  However, I might start out
students on it.  There's a big benefit to a list of suggestions as
opposed to a big blank space.
A lot of people do incomplete or incorrect work because they don't
know any better.  It doesn't matter if they're using a GUI or not,
they'll do what they think they know, and get it wrong.
