Apps Which way to choose for my app

[netpumber]

Hello.

I wanna start a project that will make a connection in a website that gives you the opportunity to send sms from web (the site is in aspx).

So this app will use a http library to send and receive GET/POST requests.

The question is how to start with it ? A friend of mine told me to use Jquery and CSS to archive my goal. Are you agree with this or its better to write it in java ?

What you suggest me ?
Also , do you know any good tutorial/book for android web development ?

Thanks in advance.
