Thanks to kind and patient help from golang-nuts, recipe is following:
1) One needs to compile Go compiler for different target platforms and architectures. This is done from src folder in go installation. In my case go installation is located in /usr/local/go thus to compile a compiler you need to issue make utility. Before doing this you need to know some caveats.
There is an issue about CGO library when cross compiling so it is needed to disable CGO library.
Compiling is done by changing location to source dir, since compiling has to be done in that folder
cd /usr/local/go/src
then compile Go compiler:
sudo GOOS=windows GOARCH=386 CGO_ENABLED=0 ./make.bash --no-clean
You need to repeat this step for each OS and Architecture you wish to cross compile by changing GOOS and GOARCH parameters.
If you are working in user mode as I do, sudo is needed because go compiler is in the system dir, otherwise you need to be logged in as super user. On Mac you may need to enable/configure SU access (it is not available by default), but if you have managed to install go you possibly already have root access.
2) Once you have all cross compilers built, you can happily cross compile your application by using settings for example:
GOOS=windows GOARCH=386 go build -o appname.exe appname.go
GOOS=linux GOARCH=386 CGO_ENABLED=0 go build -o appname.linux appname.go
Change GOOS and GOARCH to targets you wish to build.
If you encounter problem with CGO include CGO_ENABLED=0 in the command line, also note that binaries for linux and mac have no extension so you may add extension for the sake of having different files. -o switch instructs go to make output file similar to old compilers for c/c++ thus above used appname.linux can be any other extension.

set GOARCH=amd64
set GOOS=linux
go tool dist install -v pkg/runtime
go install -v -a std

It tells you it needs all tools built before you can use them.
If your windows GOARCH is amd64, then you could "build" all required tools by running this small batch programs:
set GOARCH=amd64
set GOOS=linux
go tool dist install -v pkg/runtime
go install -v -a std
If that succeeds then you should be able to do what you've described (just use amd64, not AMD64 - it is case sensitive).
If your windows GOARCH is 386, then you would need to build your 386 tools first. You would need to download mingw gcc for that. Do what user2714852 said.
Here https://code.google.com/p/go-wiki/wiki/WindowsCrossCompiling are similar instructions for linux, perhaps you find them helpful.
