Graphical user interface builder
A graphical user interface builder (or GUI builder), also known as GUI designer or sometimes RAD IDE, is a software development tool that simplifies the creation of GUIs by allowing the designer to arrange graphical control elements (often called widgets) using a drag-and-drop WYSIWYG editor. Without a GUI builder, a GUI must be built by manually specifying each widget's parameters in source-code, with no visual feedback until the program is run. Such tools usually called the term RAD IDE.

User interfaces are commonly programmed using an event-driven architecture, so GUI builders also simplify creating event-driven code. This supporting code connects software widgets with the outgoing and incoming events that trigger the functions providing the application logic.
Some graphical user interface builders automatically generate all the source code for a graphical control element. Others, like Interface Builder or Glade Interface Designer, generate serialized object instances that are then loaded by the application.

- VB6 There is the VB6 IDE itself, perhaps the grandfather of all the RAD IDEs listed here. Still operational and functional on Windows 10+ despite the 20 year neglect from Microsoft. It is still available from Microsoft by subscription. It installs with some small effort (using online guides) and produces surprisingly decent results. Being unsupported can actually be a positive as VB6 is unchanging and at the very least, stable. VB6 as a tool is limited by being 32bit in all respects but the IDE, object and code editor is still competent and extremely quick to start, compile and interpret on modern systems. The Graphic compositor is the definitive RAD builder of its time. Despite being limited to VB6 controls alone, some extremely advanced GUI designs can be still built. TwinBasic and RADBasic set themselves as true successors and aim to offer future proofing and 64bit capability whilst being fully compatible with the language. Both are building a replacement IDE replicating the GUI builder. Note: VBA is 64bit, fully supported by Microsoft and is based upon VB6.

RAD Basic is not the only game in town. Alternatives in varying stages of development include twinBASIC, which also aims to be backwards compatible with VB6 and VBA; and FreeBASIC, which implements much of what lurked in Microsoft QuickBASIC (and has a nifty IDE in the form of VisualFBEditor).
