SharePoint Foundation 2010 : Changing language settings

Question

My employer would like to offer our clients the ability to specify a preferred language in-which to use our SharePoint solution.
I.e. Clicking on a national flag on the dashboard will consequently display the system text within the associated language.
Ideally this feature will be bespoke to each given user. I.e. Default language will be English. Each user thereafter will be able to specify their unique user session within their desired language.
Is it possible to configure our solution to offer this feature? If so, how?
We are currently using SharePoint Foundation 2010.
Many thanks in advance.

The ability to display prompts in a different language in SharePoint 2013 is called the
Multiple Language User Interface (MUI).  The issue with what you are attempting is not building an interface to enable or disable a specific language in the MUI.  The problem is that the available languages are completely dependent on whether
a SharePoint Language pack for that language has been loaded or not.  If they have been loaded then its just a matter of writing your application to take advantage of Localization support through the use of resource files.  But localizing your application
without loading the SharePoint language pack for that language probably won't work well.  here's a couple articles on the MUI and localization.
