Freeing memory

[Lucas Clemente Vella <lvella triang com br>]

Running the code below:

#include <gtk/gtk.h>

void swq(GtkWidget *main_window, gpointer data){
 GtkWidget *window, *message;
 gint decision;

 window = gtk_dialog_new_with_buttons("Confirmation", 
GTK_WINDOW(main_window), GTK_DIALOG_MODAL, "Yes", GTK_RESPONSE_YES, 
"No", GTK_RESPONSE_NO, NULL);
 message = gtk_label_new("Are you sure you want to quit?");
 gtk_box_pack_start(GTK_BOX(GTK_DIALOG(window)->vbox), message, TRUE, 
TRUE, 0);
 gtk_widget_show(message);
 decision = gtk_dialog_run(GTK_DIALOG(window));
 if(decision == GTK_RESPONSE_YES) gtk_main_quit();
 gtk_widget_destroy(window);
 return;
}

int main(int argc, char *argv[]){
 GtkWidget *window;

 gtk_init(&argc, &argv);

 window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
 g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK(swq), NULL);

 gtk_widget_show(window);
 gtk_main();
 return 0;
}

I would like to know if the memory allocated to the Label Widget 
"message" in function swq() will be freed in the end of the function.
If not, how can I free it? Is just to use the function 
gtk_widget_destroy(message)?
What about the Dialog Widget "window"?
