I lost a little bit the focus on this topic but you might take a look at the various projects on Github dealing with GUIs.
The following links provide an overview of what's available today.
Qt bindings are just one way to go. As kind of an IDE for Go I'm using LiteIDE X which based on Qt. LiteIDE X runs on Windows, Linux and Mac OS X. It's quite stable and fast. You might take a look at the project on
https://github.com/visualfc/liteide to get an idea how it is done and how much work is involved.
Due to the many issues I had with almost any of the existing GUI projects I tried, I left the traditional approach and started to provide the GUI part in browser technology. I have to admit that doing so I have some open issues as well, but the problems are no longer related to dependencies and the like.
