That is true -- there are no c++ bindings for the gdl docking widget
yet.  If you wanted to start on a libgdlmm wrapper library, I'm sure
people here would be willing to help and advise.  As far as I know,
the gimp docking widgets are not split off into a reusable library
yet, so that would be a bit more difficult than using gdl perhaps.

Alternately, the gdl C widgets can be used directly if you wish.
gtkmm widgets provide access to the underlying C variables with the
gobj() function, which you can use when you need to mix and match C
and C++ types [e.g. foo_c_function(cpptype.gobj());]  The Glib::wrap
function which may be useful to wrap C widgets as generic gtkmm
widgets.  Hope that helps
