Qt Creator is an integrated development environment (IDE) that provides a full suite of tools for developing Qt applications, including a code editor, debugger, and visual designer. Qt Designer, on the other hand, is a standalone tool specifically for designing user interfaces using Qt's drag-and-drop interface.

Therefore, the government may be hesitant to undertake such a significant change. **
