Well, Lazarus is exactly what you are asking for. Its GUI designer is leaps and bounds ahead pretty much every other GUI designer for desktop applications and the IDE integration with the underlying framework is second to none. The project isn't only under active development but has more developers than it ever had.
The WinForms you mentioned feels like some abandoned beta that barely provides Delphi 1 level functionality in terms of "RAD-ness" and other frameworks abandon the entire RAD idea altogether, regressing back to glorified resource editors like you'd see in 16bit Windows back in 80s.
