I finally got the HelloWorld running, and I even managed to work my calculator applet into a proper Kindlet, and it actually works!! Finally!
I am glad I found enough information on this forum, albeit that it took me quite some time until I found the proper threads.
I am going to post the app here in this thread as soon as it is ready. Currently I am having font size problems. I'll have to dig this forum for the manifest's Font-Size-Mode attribute, I guess.
