Try Py++ GUI.

You don't have to learn any API.
This is the code Py++ generated for your ExternalLib class:

namespace bp = boost::python;

struct ExternalLib_wrapper : ExternalLib, bp::wrapper< ExternalLib > {

    ExternalLib_wrapper( )
    : ExternalLib( )
      , bp::wrapper< ExternalLib >()
    {   // Normal constructor

    }

};

BOOST_PYTHON_MODULE(pyplusplus){
    bp::class_< ExternalLib_wrapper, boost::noncopyable >(
"ExternalLib", bp::init< >() )
        .def(
            "Create"
            , &::ExternalLib::Create
                /* undefined call policies */ )
        .def(
            "Print"
            , &::ExternalLib::Print )
        .staticmethod( "Create" );
}
