I fail to see how the GUI part would suffer from lack of performance if the rest of the system is fine. I would hate to be bold, but to me this case sounds a little bit like "MVC done wrong" if the breaking GUI apart from the rest of the software is really that impossible.

A few years ago one of the architects at Adobe published some slides on the software engineering aspects of PhotoShop, unfortunately I couldn't find them on the web when I tried recently but I believe it stated the codebase was well over 1 million lines of C++ and the GUI (including Adobe's own frameworks) accounted for more than half of that...

GUI's often *are* the program rather than a way in to use it.

What about a more recent code base, this is from a 2008 presentation on Adobe Lightroom 2: - "63% of the main Lightroom-team authored code is Lua" - "16% C++" - "12% ObjC" - "9% C" http://www.troygaul.com/LrExposedC4.html
