OO in Go is quite peculiar, but not impossible. I'd even say you could quite naturally code methods and properties of components, while events would have to be a part of this particular implementation.
In any case, I completely agree: whoever decides to do it, they'll have to take Go's peculiarities into account and instead of making an exact copy of Delphi in Go, create a new project leveraging the specific features of Go and reflecting them in the GUI construction in an elegant way.
Yeah, my comment came off a little harsh. I'm not discouraging someone from creating a Go IDE like Delphi, I'm just saying that one should be prepared to make allowances for what the language can/cannot do, given that one cannot change the language. The original Delphi team had the enviable position of being able to modify the language to suit the IDE, and vice-versa.
