> Windows: 2k, 32 or 64bit, Qt, Qt5, Qt6 (64bit only) Besides Qt, does it have a pure Win API back-end as well?

  Yes. Try the IDE itself; on Windows it is built with Win API. PeaZip is a sample of it https://github.com/peazip/PeaZip https://github.com/peazip/PeaZip

    Ok, using WinAPI means it is not easily theme-able, unless they provide custom set of controls. I assume it is possible to use Qt back-end for Windows as well. I wish Lazarus also supported C++ akin to C++Builder. Pascal is a deal-breaker many.

      Custom control set is supported too, and there are multiple alternatives.

  Yes, Lazarus has a native Win32/64 widgetset (LCL-Win32) that directly uses the Windows API without Qt dependencies.
