Could you build this?
No A secure messenger with end-to-end encryption, a post-quantum key exchange, calls, and groups requires cryptographic protocol design and an audit. Mistakes are severe, and real-time calling infrastructure adds further complexity.
What it would actually take: Build on vetted protocols and libraries (such as the Signal protocol, or a post-quantum KEM with an audited implementation), plus native mobile clients, a federated or relay server, and WebRTC calling with TURN infrastructure. This needs cryptographers or experienced security engineers, an independent security audit, and scalable infrastructure. Vibe-coded crypto is a serious risk.
