I think the Java/C++ style of object oriented programming is 
particularly well suited to writing GUIs.  GUIs contain a lot of objects 
that need to maintain their state, and that need to respond to messages. 
  The different kinds of objects have a lot in common with one another, 
and also some specific differences.

You don't need an OOP language to write a GUI (the Windows Rgui is 
written in C, for example), but it makes things easier.

You can write R in that style, but it's not the standard style to use, 
so it's not particularly easy.
