Debugging Go (golang) code in Windows
In addition to GDB you can use Zeus. Also, take a look to comparison of IDEs for Google Go.
Delve supports windows and can be installed with the following command:
go get github.com/derekparker/delve/cmd/dlv
It has integration with code editors and IDEs such as VS code, Atom and IDEA. No Sublime Text support is available yet though!
LiteIDE (https://github.com/visualfc/liteide) includes a build of GDB that works on Windows. When I experimented with Goclipse, I was able to point it to that GDB executable and debug applications just fine.
