The QR Generator app is purely built in Java SE for backend and Java Swing for the UI, using the Model View Controller approach. It relies on XZing Library to build the QR and generate the 2D code image that can be exported to the local file system. To read the QR image, you will need to a QR Scanner or the many apps that can scan QR codes using mobile phone camera. Below is a typical screen of the application running, with the custom color scheme drop-down active in Windows 7. The L&F may differ depending on how your OS renders the UI components, since the application uses the System Default Look & Feel.
