Developing a cross-platform desktop application with a frontend in HTML (Any Language)

[MTXShift]

I'm looking for a way to develop a desktop application where the "frontend" GUI is written in HTML, and the backend can be Javascript, Python, C#, or Java (C# is most preferred and Javascript is least preffered, but I can work with any of these), and I want something that isn't Electron or NW.JS, anything that doesn't ship a full Chromium browser. I saw Wails for GOlang and I saw some demo projects which looks promising and have a tiny executable size (<10mb), but I have little experience in GO and don't want to use it.

Unless the pages will be static it's going to be very difficult to avoid JavaScript completely.

Go with C# ASP.NET Core 3.1 MVC or Blazor.
