Make the dialog non-modal, i.e. do not use gtk_dialog_run(),
just show_all the dialog, connect to its "response" signal
(process any user response in the callback) and let the main
loop continue.

Otherwise I'm unsure what you are trying (things such as
calling gtk_widget_hide_all() and then immediately
gtk_widget_destroy() on the dialog do not make much sense to
me).
