You can set the label to be the mnemonic for another widget.

   # new() is aliased to new_with_mnemonic() in the perl bindings:
   $label = Gtk2::Label->new ('_User Name');
   $entry = Gtk2::Entry->new;
   # set $label to be the mnemonic for $entry
   $label->set_mnemonic_for ($entry);
   $hbox = Gtk2::HBox->new;
   $hbox->pack_start ($label, FALSE, FALSE, 0);
   $hbox->pack_start ($entry, TRUE, TRUE, 0);

This sets things up so that when the user activates the mnemonic Alt 
+u (in $entry), the keyboard focus goes to $entry.

gtk_button_new_with_mnemonic() and the like essentially do this for  
you.  For separate widgets,  you have to do it by hand.
