except that they're not Widgets; they're GtkWidgets.  you also really 
want to be using an array of pointers, thus:

GtkWidget *label[12];

then you can do, for example:

label[3] = gtk_label_new("foobar");

and you won't need the explicit GTK_WIDGET() cast when passing to 
functions expecting a GtkWidget.
