You can use the admin page as a example of how to create a language select.
I copied the following code with some modifications:
web2py/applications/admin/views/layout.html
<span>{{=T('Languages')}}</span>
{{if hasattr(T,'get_possible_languages_info'):}}
<select name="language" onchange="var date = new Date();cookieDate=date.
setTime(date.getTime()+(100*24*60*60*1000));document.cookie='language='+this
.options[this.selectedIndex].id+'; expires='+cookieDate+'; path=/';window.
location.reload()">
{{for langinfo in sorted([(code,info[1]) for code,info in
T.get_possible_languages_info().iteritems() if code != 'default']):}}
<option {{=T.accepted_language==langinfo[0] and 'selected' or ''}}
{{='id='+langinfo[0]}} >{{=langinfo[1]}}</option>
{{pass}}
</select>
</span>
{{else:}}
</span>
{{pass}}
web2py/applications/admin/models/0.py
# set the language
if 'language' in request.cookies and not (request.cookies['language'] is
None):
T.force(request.cookies['language'].value)
