It will not work if you embed the C++ class within the GObject struct because the GObject struct is simply allocated as a block of memory from the heap (using GSlice or whatever but anyway no C++ new operator is involved). You can create C++ objects in the instance-init method of the GObject and then, for example, put pointers to them to the GObject struct and destroy them in the the GObject finalize method. If you just want this and not any of the fancy stuff cxx-gtk-utils does then it is quite trivial and you do not need any extra library.
