Compile a simple desktop APP (the app is already done) written in Python with CEFPython library (chromium embeded) for Mac OS and Windows

I need someone to compile a desktop APP written in Python wich has Chromium embeded and basically runs a slideshow of images thru javascript. The APP works, but i haven't been able to sucessfully compile a working version neither for Mac Os nor Windows. Mac OS version is the most urgent. It would be OK if you could take care of just one the versions (Mac or Windows) I would need the configuration file ([login to view URL] etc) to later compile by myself the final version of the APP, this is now on an ALPHA stage. Ideally i would need this to be a single executable file, but I'm open to see alternatives, the final APP will have some folders of data to load (html, css, javascript) but i need something that doesn't needs an install process, just a zip file with the ready to use APP.
