C++ on the IRIS?

[Jeff Sorenson]

I am new to both the IRIS and this newsgroup.  I'm hoping that someone who
reads this group can give me some advice.  I'm going to be working on a 
project soon which require a C++ compiler for the IRIS.  Does anyone know
of a good C++ compiler for the IRIS?  Since we want the program to be as
portable as possible, we want to implement the interface with x-windows.  
Is there a class library for x-windows that will allow me to treat 
things like windows, menus, scroll bars,and the mouse as objects? Or will
I have to create these from scratch?  Any replies by e-mail or on the net
would be greatly appreciated.
