This [https://develop.kde.org/docs/getting-started/hello_world/ first program] page was move [https://develop.kde.org/docs/getting-started/hello_world/ here].
Your first program shall greet the world with a friendly "hello world", what else ? For that, we will use a KMessageBox. To get more information about the KMessageBox-Class, type "kde: kmessagebox" in your konqueror and it will redirect you to http://developer.kde.org/documentation/library/cvs-api/kdelibs-apidocs/kdeui/html/classKMessageBox.html

#include <kcmdlineargs.h>
int main (int argc, char *argv[])
  KAboutData aboutData( "test", "test",

      "(c) 2006" );
  KCmdLineArgs::init( argc, argv, &aboutData );
  KApplication khello;
  KGuiItem kgi(QString("Hello"),QString(),
    QString("this is a tooltip"),QString("this is whatsthis"));

-I/home/kde-devel/qt-unstable/include -I/home/kde-devel/kde/include  -L/home/kde-devel/kde/lib \
-L/home/kde-devel/qt-unstable/lib -lkdeui -lkdecore -ldl     
and then run it with
