I wonder whether it would help, if dmd would improve with respect to the 
integration of C++ object code with D. Name mangling for extern(C++) 
seems almost ok, and there is a not too old patch for dmd that shows 
usage of Qt without additional bindings:

I recently played around with C++ interfaces a bit in another context 
and noticed that you can interface C++ classes like this:

// test.cpp
class C
{
public:
	virtual int virtual_fun(int x);
	int nonvirtual_fun(int x);
	
	int a;
};

// test.d
extern (C++)
interface C
{
	int virtual_fun(int n);
	final int nonvirtual_fun(int n);
}

It actually needs a tiny patch on windows (nonvirtual_fun is mangled as 
static function). Unfortunately I did not find a way to sensibly declare 
member "a" in D. There is another bug that a derived class is using a 
wrong virtual function table offset, but that should be fixable.
