How should I build a app run locally with db connection [closed]

I want to build an app, which can work without a network connection. Here are some requirements:

1. it needs to be able to talk to a local database, ideally, a portable database (I noticed SQLite could be the one I am looking for, and will spend some time to look into it) that does not need installation or configuration to use. In other words, you get a copy of the app, you start it then you can use the full functionalities.
2. I prefer to build a web app because it's easier for me to build the interfaces with CSS and Javascript or frameworks like React.
3. The server, if there must be one, should be included in the app package and portable. For example, the user might have no idea of what is the nodejs so you can't ask them to install node and start the server by themself. I had done some java code before, but not spring boot. if I build a server with spring boot, can it be started with a simple click?

what kind of technologies should I choose for DB, UI and Server? I am open to exploring any new stuff.
