The nice thing about C++ is that it is 'low level' when you need that,
and that by writing a few classes on top of this you can get _exactly_
the type of high level abstraction that you need, without the ballast of
a high level language that is designed to provide everything to everybody.

This also applies to GUI code. You need only a few relatively simple classes
on top of Xlib that take care of event polling and delivery, X11 resource
management (an area where most high-level languages break down), and a set
of widgets. Everything else will probably need a general purpose canvas and
low level drawing operations anyway, and these are as easy to do directly in
X than in any toolkit or high level language that I know of, or even easier. 

What you get is a high level interface, blazingly fast performance, and
easy integration with the time-critical code that is typical for any audio
application. Try to do that with Tcl/Tk, Python or whatever.

Just my 2 Eurocents, of course.
