GUI in C using OpenCV

Is there any simple way to create a GUI using OpenCV libra开发者_运维技巧ry or linking some other library with OpenCV.

Just Like the trackbar in OpenCV, is there any way to create push buttons also?

OpenCV is a computer vision framework, not a GUI framework (even though OpenCV contains some very basic GUI functions).

For a real GUI, better use something like GTK or Qt.

I would recommend fltk. You can get started here: http://seriss.com/people/erco/fltk/

Once you build your gui you can convert Fl_RGB_Image and IplImage types back and forth.
