Qt is a large framework and also includes e.g. a large network module which supported async event based communication long before there was Go. But it's unlikely that a Go application uses this, because Go has its own network library and even native language support for asynchronous communication (buffered channels). But Qt also has cross-platform user interface features even with 3D and OpenGl support, which might be useful for people using Go on the desktop.
