Build a Custom Vehicle Listings Monitor with GUI

I’m looking for an experienced developer to build a standalone application that monitors a UK vehicle listings platform for new adverts, based on a combination of native and custom filters. The tool should run on Windows, include a clean, user-friendly interface, and support basic alerting features.

I’m open to any language or tech stack as long as the final tool:
• Is stable and reliable
• Has a GUI (desktop preferred, not just command-line)
• Works smoothly on a Windows machine
• Meets the functionality outlined below
