Convert console to GUI application

my requirement is that i need a code to compare two images. the images can be of any size, any type, any resolution.. It has to be GUI BASED. P.S. I have the source code ready with me however there are two limitations. 1. It is not a GUI based. 2. It does not compare images of different resolution, different size and different type. Please bid if you can do the above mentioned requirements. Milestone will be done only if you can complete the above mentioned requirements and show the demo.
