Does an embedded browser exist for GTK application?

Hi all,
I’d like to embed a simple browser view/widget in my C GTK3 application.
The application is kiosk-like app so I need to remove every buttons and navigation bar, but I need to have a ‘close’ button (i guess external to the browser view).
The navigation is on an internal site.

Does exists?

You can use WebKitGTK.
