Yes, you can build cross-platform GUI apps with Delphi. However, that requires using Firemonkey (FMX). If you build a GUI app using VCL on Delphi, it's limited to Windows. If you build an app with Lazarus and LCL, you CAN have it work cross-platform.

I thought the point was that Windows apps will run on Linux under Wine (and macOS?) so using VCL is a cross-platform GUI development environment.

I made the clarification because the comment I replied to mentioned Android, iOS, and macOS. There are many who used Delphi before FMX appeared and I thought it would be helpful to point out that VCL only makes Windows executables.

You might as well use Lazarus and LCL. It'll give the best of all worlds.

> Alternatively, RemObjects makes Elements, also a RAD programming environment in which you can code in Oxygene (their Object Pascal), C#, Swift, Java, Go, or Mercury (VB) and target all platforms: .Net, iOS and macOS, Android, WebAssemblyl, Java, Linux, Windows.

Wait you can make Android applications with Golang without too much sorcery??

I just wanted to convert some Golang CLI applications to GUI's for Android and I instead ended up giving up on the project and just started recommending people to use termux.

Please tell me if there is a simple method for Golang which can "just work" for basically being the Visualbasic-alike glue code to just glue CLI and GUI mostly.

Why don't you try it out: https://www.remobjects.com/elements/gold/

It's really price-y and I am not sure about if I could create applications for f-droid if they aren't open source and how it might go with something like remobjects.com/gold/

One of the key principles of f-droid is that it must be reproducible (I think) or open source with it being able to be built by f-droid servers but I suppose reproducibility must require having this software which is paid in this case.
