    Well, if you want to make your desktop application work without internet, you need to have the whole list of words in both languages and the relation between different words of two languages.

    It is not possible to connect to google without the internet...
    As the previous poster indicated, the only way to achieve what you want is to somehow get all words from language1 and all words from language2 and store them locally on your workstation. You would then need some way of determining relationships between words (for example "jump" in english maps to "sauter" in french).

    With this information you would then need to generate some trees or hashmaps which allow you to get the word from language2 that maps to the word from language1 and vice-versa.

    Basically if all you want is to use your GUI to call google api functions, then you MUST have access to the internet. Short of that, you're pretty much stuck completely re-writting the google api functions you intend to use.

    Well, rektiphyr, you can't see if it's the only solution.
    @sciences: There are many dictionaries available. You can either use the dictionary in order to get results.
