As I promised in [the thread about](https://discourse.julialang.org/t/step-by-step-instruction-and-example-how-to-create-standalone-applications-for-windows-with-a-g-ui/128274/1) the instruction how to create standalone applications with a GUI, here is as example a complete GUI program that was created using _[PackageCompiler](https://github.com/JuliaLang/PackageCompiler.jl)_ + _[Lazarus](https://en.wikipedia.org/wiki/Lazarus_(software))_.  
(I selected Lazarus as UI because it is platform-independent and one is quick to make a fully-featured GUI.)

The program is part of a package I wrote for a new algorithm to cluster data (called “Iteridense”). I wrote the algorithm completely in Julia as a module. This module is compiled to a library as described in the above mentioned thread. This library is used by the Lazarus program.

- You find the Julia module as package [here](https://github.com/donovaly/Iteridense-package).
- Inside of this package you find the module adapted for compilation as C-callable library [here](https://github.com/donovaly/Iteridense-package/tree/main/IteridenseCLib).
- The Lazarus program can be found [here](https://github.com/donovaly/Iteridense-package/tree/main/IteridenseCLib/IteridenseClustering).
- If you are interested to have a look at the final Lazarus program without compiling it, you can download from the [latest release](https://github.com/donovaly/Iteridense-package/releases) assets the file _IteridenseClustering.zip_. There you find in its _bin_ folder the file _IteridenseClustering.exe_ file that can directly be executed under Windows (no installation or admin permissions necessary.
