I'm not sure what is it exactly that you are looking, but if you are interested in doing development in Qt, check out the QNetworkAccessManager class here: http://doc.trolltech.com/4.6/qnetworkaccessmanager.htm

If you are completely new to Qt, you should probably google some Qt tutorials first... And also check the wiki about Qt on maemo.org here: http://wiki.maemo.org/Qt4_Hildon

A fair amount of tutorials/howtos are also found on forum.nokia.com

If you are not interested about developing with Qt, then someone else can probably point you to the right direction...
