Just to clarify my (admittedly controversial) opinion. I didn't mean that good GUIs can't be embedded within R, I meant that if you need to do something that goes beyond placing widgets in a window, you probably will want to write the GUI code in another language and call it from R. For example, speedR's GUI interactively calls R but is written in Java.
