Difficult to run without go modules #36
Description
go get doesn't do what it used to do and go install complains there are no modules present in Go >= 1.18...
I ran go mod init gotk3/gotk3-examples in the root of this repository and then go mod tidy.
Then I could run go run -v ./gtk-examples/simple/simple.go.
First build was quite slow, could be documented as such.
Shall I submit a PR?
