Build me a simple desktop app that lets people pick an OS image file and flash it to an SD card or USB drive safely.

It should make the whole process feel easy and hard to mess up, with a clear drive selection step so nobody accidentally wipes their main hard drive. After flashing, it should verify that everything was written correctly and show a clear success or failure message. I’d also like it to support common image formats and work on Windows, macOS, and Linux.

If possible, include a friendly modern interface, progress feedback, and a way to handle Raspberry Pi devices that boot over USB. Make it something that feels polished and trustworthy, not a technical tool. Use current docs online if you need to.
