title: How to make a GUI in QT using visual studio?
body: <p>I have c++ code which uses GDAL libraries to do some operations in an image (like slope, aspect, hill shade etc).  Now, I want to make a GUI in which I want to fetch 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.</p>
  
  <p>Many people have suggested me to use Qt. I have built and installed Qt in my  visual studio 2010 successfully.</p>
  
  <p>Please help me how to proceed with the GUI. I have intermediate skills in C++ programing and new for GUI applications.</p>
