We could build an hash table that maps the C define to the string, but is 
this hash table useful for programs other then yours? I think it's not.
Let's see.
Now:

$stock = Gnome::Stock->button('Button_Ok');

Alternative:

$stock = Gnome::Stock->button($Gnome::Stock{'GNOME_STOCK_BUTTON_OK'});

Note that you have to lookup both Button_Ok and GNOME_STOCK_BUTTON_OK
int the c header file.

Write a script that generates the hash table in the build process of
the Glade module from the header file.
