Questions regarding this project

[Raj2032]

Hi, I have some questions regarding this project:

1. Can I make regular GUI applications (such as menus, buttons and stuff) or is this more aimed at computer graphics design art work?
2. Is this cross compatible between Linux, Windows, web version and Android (write once run everywhere)? If it doesn't support all of the mentioned platforms which platforms does it support?
3. If it supports web version would it be a web application, or html/css or both?
4. Is it well maintained?
5. Does it give me the ability to make my own custom UI, something like this for example:

6. And can I mimic Android's native UI?
7. Is there a chat platforms such as Discord or Matrix (Element) for this project?
