GTK+ is also a third party library. I can easily use it in any language 
and the resulting binary will be really small. In D a small hello world 
GTK+ GUI application was 2 MB, IIRC, when I used the bindings available 
somewhere.

And D depends on some basic C libraries, I might guess. Agreed not 
everyone has Java installed, but when the end users have it, it's a large 
advantage to ship small binaries. If you host the binaries on the web, 
you can cut off 95% of the traffic expenses pretty easily by shrinking 
the distributables.

It's by all means ok to have few bloaty application on a system, but 
image if all programs started to consume 1000x as much space as now, 
software like Windows 7 would require 10 TB of disk space.

That's because you use windows.. it stores only one instance on *nixen - 
thanks to sane package managers.
