what do you need to do exactly with it? for instance for string conversation you can just simply use QString function do to that between simple c/c++ string/char.
If not QT than which one i should prefer, please a detailed answer
when you have C codes, and you need UI/gui stuff which toolkit will come in to scene? in my opinion Qt
Actually what you need is just some researching (googling ) and yay!
