Use it directly

go build -ldflags="-H windowsgui -w -s"

Will be an error , The reason should be related to the call of the Library .
Change to the following format

go build -ldflags="-linkmode internal"

Of course, if you want to remove the black box, you can use the following code to compile

go build -ldflags="-H windowsgui -w -s -linkmode internal"
