Yes, it's an advantage (speed and memory). No, you might not need it.

Yes, D can call all C libraries that it has an "import module" for.
Generating these is somewhat tedious, but it can be mostly automated.

Unfortunately, most libraries for GUI development are either written
in C++ or use unavailable system libraries which makes using them hard.

Why not ? If you already have a C/C++ and Python background, it
shouldn't be long before you decide whether you like it or not.

There is room for both. And D is more "up against" C++ than C# ?
Having the GDC->JVM compiler (like Managed C++) would be nice...
