If you really want to develop for both MorphOS and AmigaOS you would need to learn C/C++. In my view both are not really beginner-friendly so Hollywood offers faster success and is much easier to learn. Also taking courses on university is too far and will not make you happy (propably). You could perhaps buy a book and start there or search for courses in web. Then you see if it is something for you or not. Courses on university are certainly not easier. And of course learn Hollywood. In my view best way to learn something new search for a limited project and try to do it. If you have problems ask.
