API for translating text

Hi everyone.
Can anyone help me in translating text from database?
I was thinking if there is a free API to integrate into PHPR project?
My problem is that I need to translate text which is stored in different table fields and I need to translate it in several languages -faster as possible- and with -less user interaction as possible-.
All translated text has to be saved in another database table. Let me show you an example:
Table for English Table for German
English: German:

1. Main text: "This is main text" 1. "Dies ist der Haupttext"
2. Sub1: "This is other text" 2. "Dies ist ein anderer Text"
3. ...
4. ...
   The point is, there are people included from all over the world. When a supervisor "click" translate text should be translated into other languages and other people could read it.
   I cannot think of easier way to do it... Selecting translation in browser is not an option!
   Any advise is welcomed!
