Auto-click / Auto data fill

Build an application which will click on a specific image on a given website every N seconds (should be variable the end-user can define). With every click on a specific image, the application will scan the screen to search for a pre-defined string. Once the string is found, it will stop auto-click and screen-scanning features and will populate input fields based on the information stored in a remote MySQL DB. Afterwards, the end-user can restart the process cycle manually. Needs a simple GUI and ability to work under x64 Windows 7 platform. Should be a straight forward project for developers with experience in this kind of field.
