That link, while fully explaining what is necessary for multiple languages, is a bit overkill - unless you really want separate menus to show which language is currently selected.

If so, create each possible page, with the appropriate graphics. Say you have the main page, and the default is "English". If you want someone to choose Czech, then create a VTS command in between the two menus, switching to the appropriate language.
