The hardest part is the syntax highlighting itself, because you need (ideally non-strict) parser and highlighter for each language. There are several languages that use PetitParser for both. Then you basically build up the text with `Text`, (`Text` class supports things like specifying color, emphasis, etc.). And then you can just show the text in a RubTextArea. You can even use Spec' TextModel; I used TextModel and PetitParser based highlightning for coloring my DSL, but I never got around to finishing it. I believe Johan's Live State Machine editor does something similar. Also look at Pillar support (I saw mails floating around that it was updated or something).
