A peculiar aspect of Lazarus (Free Pascal's Delphi-like IDE) is that it either cross-compiles for other architectures or can run itself on them, therefore generating native GUI software that runs immediately on the target platform. That is, you can develop ARM executables on a Raspberry PI using Lazarus running on the Pi itself. I would also suggest to take a look at FPCUpDeluxe, an installer that does all the tedious job of dealing with dependencies for installing FPC, Lazarus and a great number of modules and components.

A personal dream: having something like Lazarus that works with other languages too; that would likely become a game changer for desktop apps development.
