Qt for beginners
I made a tutorial how to install Qt for Linux (made it specially for openSUSE, but there is no bigger difference, than a repository link) and a hello world example with the Qt Creator.
For those who need SVN, there is a great tutorial how to get it run. For the people who want to get over a "Hello World" is also a example how easy an application is made to convert binary numbers into decimal and back.
