Fowl is a tiny GUI toolkit that loosely reimplements the OWL toolkit from Turbo Pascal for Windows in Free Pascal, though it is not 100% the same. It only implements a subset of it but it can be used as an alternative to Lazarus/LCL for when you want to create a small Windows-only executable.
Download Fowl 0.1 here (32KB). Currently the only documentation is the readme.txt file which provides an overview of the API and a couple of examples.
