Learn from the experts!

            


I would like to achieve based on SMTP / POP3 encrypted mail on the mobile platform, I now symbian technical aspects in this regard, there is no understanding, because never come into contact, if it is seen as a language to learn, I think symbian and other difficulties encountered in the process of learning the language is similar, so the learning of language is concerned, I'd nothing to worry about.
I am confused is that such a software implementation, I need to do to start from somewhere, what aspects of the knowledge required to achieve it, or rather, what steps should follow to achieve it, it is more concerned about me, And after such a feature of the software if achieved, what is the actual value of what, for example, my software in what direction should be distinctive in order to have meaningful applications, this is my greatest concern,
Further still, if the experts think that this program is not valuable practical applications (for example, now other similar features of the software have done well, I have not been necessary!) What's more meaningful What good idea of software development, experts advise!
Thank you for your support!
