QR Code Reader “Shell” minimal Web application

Web based application intended to be a very simple minimal “shell” or “prototype. It should be as simply written as possible for easy learning and modification by me. It should 1. provide option to set the application in English, French, German mode based on a drop-down list of languages. List of languages specified as Language,Abbreviation format in the scanning application. File, say as Languages = “ EN=English,FR=French, GE=German” and I should be able easily modify that. 2. once a language choice was set that should be remembered locally and should be changeable by use via the Web page with same drop-down list and a Set Language button. 3. obtain a QR code from a local image file or built-in camera based on two buttons respectively scan the code 4. send the code and the abbreviated language code to a very simple a PHP or Python Web server application 5. the application should send back to the browser an HTML file say [login to view URL], [login to view URL] or [login to view URL] based on user language choiceThe page content should be very simple – for example Example: Code: 123456bc where 123456bc is the scanned QR code
