No other RAD claiming IDE has the same RAD capabilities as Lazarus or Delphi (or C++ builder), including QT Creator. Live database connection and manipulation while designing your form and data module? Nah, it doesn't even know what a data module is.
QT is really expensive for commercial use though. And it's not as easy as Builder was. Builder basically gave you Delphi capability but in C++. You could focus 100% on the problem you're solving rather than on the UI -- true component based RAD. Drop a few components, wire them together, then add your code to do what they can't do.
