Hi Alexis, as a quick hack, you could pass create_center() the widget it 
is to build inside, and have it return the text box

     GtkWidget *
     create_center( GtkWidget *parent, const char *label_text )
     {
       GtkWidget *label, *text, *hbox;

       hbox = gtk_hbox_new(...
       gtk_container_add( GTK_CONTAINER( parent ), hbox );
       label = gtk_label_new( label_text );
       gtk_box_pack_start( GTK_BOX( hbox ), label ...
       text = gtk_entry_new(
       gtk_box_pack_start( GTK_BOX( hbox ), text ...

       return( text );
     }

a better solution is maybe to make your own widget (called LabelledText? 
something like that), it's pretty easy:
