Cons
Con Developed by a single person
Statistically, apps being developed by a single person can be gone without warning.
Con Strictly C++
Con This is an application development framework not simply a GUI toolkit / library API
It is designed for you to develop your whole application using it, not just your GUI. Most people probably are not really looking for that.
