That doesn't sound too complicated, or maybe I'm mistaken? For one of my applications, I needed HTML rendering once, which I implemented by creating a delegate holding a QTextDocument. The delegate just sets the text on the document and then draws its contents. The same should work when you set a highlighter. Like this (sorry, not the cleanest code, it's already a few years old): http://pastie.org/p/6yTw8HZl47KcgvrjSBaDG8
Otherwise, I'm not sure either. I personally think it will be easier if you just use a QTableView, unless you need column-wise text selection. I think you could hook everything you need into KTextEditor as well (by e.g. setting custom context menus depending on the column that was clicked etc) but it will require more lines of hacks than you would otherwise need to re-create the needed functionality yourself ;)
Some applications use the text editor for a lot of stuff, maybe that can serve you as inspiration -- e.g. sublime text comes to mind, which presents its search results (and probably other things) as an interactive text document.
All the best,
