Lazarus and Delphi have the most intuitive UI builders of all the tools I have every tried. Lazarus components can be anchored relative to the parent and to each other. Latest Delphi has various layout panels - stack, relative, grid. Both tools feel fast and responsive (even on older hardware) which is something that I haven't experienced with any .NET or Java tool I had to use. Both tools have been around for a long time and haven't changed or abandoned underlying technology every few years so projects built 10 years ago can still be used with latest versions, sometimes just recompiling is enough.
