I know you say you don't want to mess with the command line debuggers, but Go works with gdb [1]. While gdb looks daunting and antiquated at first, once you learn your way around, you'll feel something is missing from IDE based tools.
This is probably very obvious, but just a note for anyone interested in using gdb.. if you downloaded 64-bit go, you need to use the 64bit gdb to debug it
If you attempt to use the 32 bit gdb, you'll get errors about the executable you're attempting to debug is in an invalid format
