Unless you're already good at C++, just about any other language is going to be faster
to program in.  Programmer time is more valuable than machine time these days for
the majority of applications--and for small- to medium-sized programs, no one is going
to notice the difference in execution speed between one and three milliseconds anyway.

If you love C++ and are good at it, that's fine, but don't try to impose your preferences
on others.  In return, I'll spare you my rants on why it's suboptimal. ;)

I'm 98% sure that kdebindings is an integration package for kdelibs rather than QT3
(or at least, I know of other QT packages for Java. Perl, etc.)  In theory, it should be
possible for a programmer who needs this stuff to rewrite a given set of bindings
using the target language's integration system, but my experience with doing things
like that suggests that it would be so painful that most just wouldn't bother.

Any interpreted language is going to be a bit slower than a compiled one because the interpreter takes
time to start up (and bytecode is still interpreted, it's just interpreted faster).

Java is in a weird sort of situation:  after the interpreter startup lag is discounted, the core of the
language actually benchmarks quite well in terms of speed (better than compiled Pascal for the 
most part, and almost competitive with C/C++), but several of the libraries are abysmally slow.  
Unfortunately, Swing, the default GUI library, is one of those (and the default file IO and 
networking packages are no great shakes either).  Result:  a lot of very slow interactive Java 
programs, and an unfairly bad reputation for the language.  (It also eats a lot of memory, but
that's another story.)

That doesn't help you with Deskzilla unless you can convince its maintainers to rewrite its
GUI portion using, say, Eclipse's SWT, though.
