From https://gnustep.github.io/ https://gnustep.github.io/ "GNUstep provides a robust implementation of the AppKit and Foundation libraries as well as the development tools including the advanced interface designer Gorm (the InterfaceBuilder) and the IDE ProjectCenter (ProjectBuilder/Xcode)."

I think it was available as a desktop choice for Ubuntu 12.
