Create desktop application from existing php script

I have a php script which currently runs on a website, I want a desktop application created which perform sthe same functions, I can supply the source code for the php script I also want the application to have a few extra features: 1. Display simple text link ads 2. Required a simple access code to be added for activation 3. User must enter email address to receive activation code 4. Features 1,2 and 3 above should be edited using a brander, I require that the brander be created as well I have another product that I can show as an example for features 1, 2,3 and 4 that will clearly show how this works Update Jan 15 The script can be seen running on this website <[login to view URL]> I have decided to simplify the project for the moment, I just want the script to run on a desktop application without the extra features that I listed above (that will be phase 2) I do not know exactly what language this should be programmed in but it needs to be simply installed on PC's using common operating system should as XP, windows 7 etc I expect there to be 3 files: [login to view URL] (config file) [login to view URL] (application) [login to view URL] windows installer package) There are additional notes on how this tool works on this page <[login to view URL]>
