Hey!

Wasmer does not support GUIs out of the box. There are two ways you can use WASM to do UI:

• Loading and running a WASM module in the browser or an electron app, which I guess is not what you're trying to do, or
• Have bindings to the host OS, similar to WASIX, which let WASM modules call into the OS to create windows and draw things.

The second approach isn't implemented in Wasmer (or any other WASM runtime I know of), primarily because there is no standard way to render GUI that works across all operating systems, so it's very difficult to standardize an interface that runtimes can implement.

TL;DR no, Wasmer does not support GUI apps at the moment.
