Answer 1

Anyone to give me the direction in that question..

Answer 2

C++ has got many libraries for GUI and I would suggest using any one of the.
I personally prefer using Qt (pronounced Cute) which I guess is really well integrated.
The good thing I find about Qt is the QML(Qt Markup Language) which is a very intuitive way of designing a GUI.

Answer 3

win32 api (win32)
mfc (win32)
wtl (win32)
qt
wxwidgets
embarcadero
gtkmm
fltk

i personally use win32 (windows) api, which gives full control. besides all of these x-platform libs call win32 api at the end.
