If you want a PDF that can be generated on the fly, I would recommend using LaTeX, but then it wouldn't necessarily be portable by default. You'd have to figure out how to bundle the basic requirements from LaTeX for the generation of the PDF document into your application. You could also probably use LaTeX with QT by using this C++ library https://github.com/NanoMichael/MicroTeX. There is a reason GUI applications are not as plentiful as console applications and also why most GUI versions of solid console apps are not up to date or buggy. It's not an easy thing to achieve, but if you have the patience for it, I say go for it!
