It's just a simple adapter. While in regular Zope 3 you register it via 
the <adapter /> ZCML directive, you simply inherit from grok.Adapter in 
Grok. That's about it.

Untested::

   import grok
   from zope.publisher.browser import BrowserLanguages

   class BrowserFormLanguages(BrowserLanguages, grok.Adapter):

       def getPreferredLanguages(self):
         langs = super(BrowserFormLanguages,
                       self).getPreferredLanguages()
         form_lang = self.request.get("ZopeLanguage", None)
         if form_lang is not None:
             langs.insert(0, form_lang)
         return langs
