I'm almost sure that you have to use Qt for that, design you UI with QML and implement a method with Qt (using QNetwork module), then all the method from Qt, you can read about this in

http://doc.qt.nokia.com/4.7-snapshot/qml-extending-tutorial-index.html
http://doc.qt.nokia.com/4.7-snapshot/qtbinding.html

Edit:
Basically you write a class that hinherits from QDeclarativeView, then you create an QDeclarativeContext and then you send the whole class to QML with

@context->setContextProperty("Main", this);@

then in QML you can do

Main.method()

Hi,

From within QML you can use "XMLHttpRequest":http://doc.qt.nokia.com/4.7-snapshot/qdeclarativeglobalobject.html#xmlhttprequest to make network requests.

You can use the XMLHttpRequest (sorry @mbrasser , your link is outdated) which implements the W3C XMLHttpRequest API

So, all you need to do is:

var req = new XMLHttpRequest();
req.open("POST", "http://www.xxxxxxxxx.com/test/test.php");
req.onreadystatechange = function() {
  if (req.readyState == XMLHttpRequest.DONE) {
    // what you want to be done when request is successfull
  }
}
req.onerror = function(){
  // what you want to be done when request failed
}

Then when you want to send a request, just call :

req.send("name=xxx&email=xxx&message=xxx");
