If you want to invest some time into it, you can use a PHP language system.
in the header of the page basically do:
include('languages/'.$_GET['language'].'.php');
and in languages/english.php do:
$lang['homepage_text'] = "Welcome to my website!";
and replace your Welcome to my website on your homepage with
<?=$lang['homepage_text']?>
then duplicate this for all languages you wish to support and do some translations in Babelfish/Google.
