Vam-Jam/Kindlet ? reverse-engineered prompt

Build me a simple Kindlet starter app for a jailbroken Kindle 4th gen, using this template. I want it to compile with the older Kindle compatible Java setup and be easy to deploy to the device with the existing build script.

Please make the app show a basic welcome screen on the Kindle, with a title and a short message so I can confirm it is running. If it makes sense, add a simple button or a tiny bit of interaction that proves input works without relying on anything too modern. Keep it compatible with the old Kindle limitations in mind, since I know a lot of newer Java features and network stuff can be flaky.

Also make sure the project still works as a clean template, so I can swap in my own code later. If there are any spots where I need to edit local paths or device settings, leave clear comments in the right places. Look up current docs online if you need to.
