Could you build this?

Partial A Markdown note app with Obsidian-style linking is buildable, but doing it natively in Rust with the GPUI framework, which has sparse documentation and a steep learning curve, makes vibe coding considerably harder and the editor performance needs careful engineering.

What it would actually take: Use Rust with the GPUI UI framework, a Markdown parser such as pulldown-cmark, a file-watching layer and a link/backlink index (e.g., SQLite or an in-memory graph). Hard parts are GPUI-specific rendering and text-editing performance and Obsidian vault-format compatibility, which call for experienced Rust and native UI developers.
