Depends on the platform you've installed opencv

If built from source the lib files should be in C:\opencv\install\x86\vc12\lib or wherever install folder would be in your opencv build folder. A simple search for the .lib file in your windows explorer will also lead you there.

With the tutorials available on opencv look at how to convert CV::mat to bitmap. Should be relatively easy to map all together into a nice GUI
