        You do the following (assuming that in the fuction that you are doing
it in you have a widget which is part of the same tree of widgets as
the one you are looking for):

        GtkWidget *localwidget = lookup_widget (button, "dialog1");
        (assuming button is a GtkWidget * and is part of dialog1)

This will return the pointer to your dialog1 widget.

        You can use gtk_entry_get_text to do it:
        gchar *entry1_text = g_strdup (gtk_entry_get_text (GTK_ENTRY (entry1));
        gchar *entry2_text = g_strdup (gtk_entry_get_text (GTK_ENTRY (entry2));
