I’m glad to tell you my new plugin Gambit Arrow Custom Front End Translator is available on the WordPress Plugin Directory.
A supplement to the qTranslate plugin which also works independently, Translate words written directly on HTML source code, Custom Words Translator for Front End Words on HTML(portuguese, english, spanish), can be customized for other languages on demand
This plugin uses the global variable from qtranslate to work, but may also work using $_GET[“lang”]
It was designed thinking ok portuguese, english and spanish, but I can customize it on demand for you to other languages
It uses jQuery to perform replacement of words written directly on HTML source code.
Hope it will be useful for you!
