I think calling only wndCurrent.Destroy() should be enough (it should be disposed
and hidden as a side effect).. that is besides the point...

It will be faster if you create your windows once at initialization
and just show/hide them, alternatively; you are probably better off
with a GnomeDruid type of design; if GnomeDruid is not available to you;
you can simply use a GtkNotebook and hide the tabs, use forward/backward
buttons to navigate pages in your notebook.

Note that libglade does a two-pass parse; it parses the glade file into
internal structures and then builds the widgets based on these, the future
gtk builder should be faster in this respect.
