Sure, you can build the dialog at startup time or on demand
the first time, but just hide it and show it on demand.

GtkBuilder works pretty much the same way, but GTK+ now inherits the
parsing code, so you cannot build a GTK+ interface from a GtkBuilder
format file without running the actual parsing code from the widgets
(which I guess is one thing libglade provides that GtkBuilder does not;
the ability to compile the glade file into a binary and completely
replace the parser).
