        I think that widget names are only for
theeming purposes (or at least thats
all I've used them for).

        You dont attach signals to widgets;
widgets come with signals. if you want to connect a handler
to a signal emitted by that widget; all you need is the
address (returned by g_object_new(G_TYPE...)).

        if you add the widgets to a container implementation
(i.e. A window) than you dont really need to worry about
freeing them. (they become the property of the container
unless you hold an explicit reference on them).

so basicly you want to:

widget = gtk_???_new(...);
g_signal_connect(... widget ... handler ...);
gtk_container_add(GTK_CONTAINER(container), widget);

if you want to remove that widget from the 
container before the container is destroyed you'll
need to hold on to its address.
