Here is a Qt Example from Forum Nokia for friends of Friendfeed.
Description: This Qt C++ example application is a social networking application that integrates to the FriendFeed microblogging engine. QNetworkAccessManager is used to access the FriendFeed RESTful API to retrieve and post XML data which is parsed using the SAX parser. Though optimised for various screen layouts and input mechanisms, the UI relies on Qt cross-platform UI components. Their appearance is modified using CSS style sheets. The application has been tested to work with touch UI and keypad,on Symbian^3 and S60 5th Edition with Qt 4.6.3. and on the Nokia N900 with Qt 4.7.0.
For more information and Maemo and Symbian^3 version see on Forum Nokia
