best way to translate a backoffice

One way this is done is define all of your text as variables as follows:

$MOD_NEWS['TEXT_READ_MORE'] = 'Read More';
$MOD_NEWS['TEXT_POSTED_BY'] = 'Posted by';
$MOD_NEWS['TEXT_ON'] = 'on';

That would be your English module (e.g. en.php) You then produce a module with the same variable names with the appropriate translated text for each of the other languages. The French version (fr.php) would look like:

$MOD_NEWS['TEXT_READ_MORE'] = 'En savoir plus';
$MOD_NEWS['TEXT_POSTED_BY'] = 'Posté par';
$MOD_NEWS['TEXT_ON'] = 'à';

These all reside in a languages directory and you include the appropriate version based on a system-wide parameter for language that you set in a config module.
