I’ve wrote a simple plugin for KTextEdit (Kate, KDevelop, and other programs that uses the KDE text editor component) that provides code completion for Go, by using gocode as backend.
I’m using it with Kate right now, and I’m happy with the results: gocode is quite efficient, so the completions appears fast and the memory usage is reasonably low. Feedback is always welcome.

Below are some screenshots of the plugin in action:
