Building an interative Desktop-like application using a web-framework

I am at the conception stage of an idea to build an interactive application on a single board computer raspberry-pi. This application is standalone and will not be connected to any network (internet)

I have experience with LINUX and it is the operating system i want hosting my application.

I have read about native GUI frameworks like GTK and QT. They seem to be effective but will require c++ skills.

It occurred to me that, with my current web development skills, i can create a local server (asp.net core) and create a web application (HTML / CSS / JAVASCRIPT) as the front end.

The web server (asp.net core) will then be responsible for all the native system accesses (GPIO etc)

SO my questions to the community is this

1. Is there a specialized web browser for this kind of software architecture.

2. Is it a common application pattern

And any other comments and suggestions are welcome
