this question should better be asked in one of the mailing lists at 
www.aosd.net, because it is not directly related to AspectC++.

We use AspectC++ to implement several aspects in operating system (kernel) 
code like synchronisation or the architecture of device drivers. I am also 
experimenting with aspects that make normal single-threaded code 
multi-threaded. In all cases I found aspects very useful. This is especially 
true if the program components should be reused in many different system 
configurations (program family concept). You can find our publications on 
www.aspectc.org.

Concerning GUIs I remember that some months ago somebody compiled a Windows 
GUI application with AspectC++. This was a difficult task. So I think that 
there must have been a reason for him... Perhaps you get a better answer at 
www.aspectj.org. AspectC++ still has a big problem to parse the header files 
GUI libs like QT, wxWindows, etc. Thus, it's not ready for GUI applications, 
yet. However, I am optimistic that the new parser will help.

Yours,
