AJAX LANGUAGE TRANSLATOR (Based on Google Translate API)

I would like developed a simple AJAX module that translates words into the Swahili language, using the Google Translate API. This module has only 2 main purposes: i) Translate words from Any language into Swahili ii) Translate words from Swahili to English The interface should be direct and simple. In terms of graphical design, the module is intended to fit in a sidebar for a website, and therefore the interface should be relatively small.
