Websphere Portal Installed Languages

Is there a way to dynamically loop through the languages that are currently installed on the Websphere Portal server? My boss would like a content viewer portlet that I am internationalizing to be able to automatically pick up any new languages that are installed in the portal, without me having to go back and make a code change to the portlet. For example, if they were to install the Finnish language on the Portal, I'd like to be able to detect that this language is available without having to recode the portlet.
