Xojo

Xojo is a rapid, cross-platform development tool that allows you to build for Mac, Windows, Linux, as well as for web, iOS, Android and Raspberry Pi. 

The Xojo programming language is both modern and object-oriented. It supports inheritance, interfaces, polymorphism and is strongly-typed as well. Xojo apps don't have an interpreter or virtual machine - they're compiled to machine code for fast execution and the protection of your intellectual property. Xojo uses native controls so your app looks and feels right on each platform.
