RadBuilder is an excellent RAD (rapid application development) tool with a fully visual integrated development environment (IDE). It is primarily used to quickly create interactive multimedia applications, database applications, and Web applications for Windows, without writing any code. It is so easy to learn and use that it can be picked up quickly by beginner developers without any programming experience.

Xojo is an unpopular but interesting integrated development environment for cross-platform applications. It can write native applications (that is, executable files in various formats that consist of instructions that can be executed directly by the CPU) with a graphical user interface for various operating systems and platforms (desktop, mobile, web and Raspberry Pi), as well as console applications, background service applications and web applications that do not have a graphical user interface.
