Hi,

  You could make your wms layer wfs compatible and make a getFeature 
request when your page loads.  Then, for each returned feature, get the 
'name' and 'bbox' of the feature's geometry and populate your combobox 
using DOM.  I made something similar in the past (1).  The only 
exception is that I found the getFeature resquest a bit heavy, so I made 
a small mapscript script that would only return the name + geom of 
features I needed.  I made it the same format as OpenLayers.Format.Text 
(see what getCities.php returns in firebug).

  Or, you could also take a look at the Shortcuts and Recenter examples 
of MapFish (2) (if you're thinking of using ExtJS in your application).  
Shortcuts works "client-side" only and you need to manually set your 
data (like above).  Recenter uses a server-side application to do the 
queries (mapfish-server).
