gtk_signal_connect have as last arg gpointer (gtksignal.h):
guint  gtk_signal_connect                 (GtkObject           *object,
                                           const gchar         *name,
                                           GtkSignalFunc        func,
                                           gpointer             func_data);

pointer to any type of data structure can be casted tp gpointer, which is
equal to void*

this should help.
