If you just want to manage the lifetime of a GtkWidget object using C++
constructors and destructors by containing the Gtk+ object within a C++
object, and add your own interface or specialisations to the GTK+
object, there are some very thin wrapper classes here which will do
this:  See in
particular the WinBase class.

gtkmm automatically wraps all the C object's methods into C++ methods,
whereas WinBase assumes you don't want to do this or that you will do
it yourself.  It depends entirely on what you want from it, how UI
intensive your application is, and how rigorously "C++-ized" you want
GTK+ to become.
