To give you some perspective for where you're coming from: it's like you're inquiring whether it's possible to write a GUI app on Windows in C without all the complexity of Visual Studio tooling and WinForms Builder. You also don't want to be bothered with dependencies. That's essentially what you're looking at here. A very small standard library and you have to reinvent the wheel for a lot of things that should exist out-of-the-box. Sure if it's a single page "app" with just a form you're gonna be fine. But what if it's expanding to two pages? Suddenly you have to maintain at the very least a separate header for two html pages including all meta and resource tags. Web Frameworks take care of that. So my advice would be to at least look at static site generators if you think this is where the project is headed.
