I'm not sure if this works, but it's worth a try:

struct HWND_PyInt {
	static PyObject* convert(const HWND& h) {
		return PyInt_FromLong((long) h);
	}
};

BOOST_PYTHON_MODULE(nrx)
{
    to_python_converter<HWND,HWND_PyInt>();
    ....
}

I'm sort of curious why you need to access the HWND as an int though...
