How to load a .app file into iTunes for Windows?

I have an app GotYou.app on my Mac, which seems to be a single file (I know it is not, but appears to be so). And we can just drag and drop it into the iTunes on Mac. But when I copied it into Windows OS for copying that into another iTunes - It appears to be a small file along with a folder. How can I copy this into iTunes so that I can install this into an iPhone?
