I have c++ code which uses GDAL libraries to open the image and do some operations on an image (like slope, aspect, hill shade etc). Now, I want to make a GUI in which I want to open an image from the directory. After that I want to apply operation on the image (assume as slope - c++ code) and then I should get the output.
Many people have suggested me to use Qt. I have built and installed Qt in my visual studio 2010 successfully.
Please help me how to proceed with the GUI. I have intermediate skills in C++ programing and new for GUI applications.
