wxFortran: Fortran bindings to wxWidgets GUI toolkit Jacob Williams released wxFortran, an MIT-licensed open-source Fortran interface to the wxWidgets GUI toolkit, published on GitHub and described as an AI-assisted creation with a small C++ layer that users never need to touch directly. The project, which Williams labels experimental and a work in progress, follows qt-fortran and lets developers write a GUI entirely in Fortran; forum commenter jorgeg noted it is now one of at least three open-source Fortran GUI options, alongside gtk-fortran, and praised the MIT license over GPL/LGPL for avoiding adoption friction. Announcing wxFortran https://github.com/jacobwilliams/wxFortran : modern Fortran interface to the wxWidgets https://wxwidgets.org GUI toolkit. Similar to qt-fortran https://github.com/jacobwilliams/qt-fortran , this is an AI-assisted creation written in Fortran there’s a small C++ layer but the user never has to use that directly . So, you can write your GUI completely in Fortran, because why not? Standard disclaimer: work in progress, experimental, etc. 1 Like Not too long ago, there were no open source options for writing sophisticated GUIs in Fortran. I think gtk-fortran was the first? Now we have at least three: jorgeg https://fortran-lang.discourse.group/u/jorgeg 3 The MIT licenses are a great thing. Shipping code with GPL/LGPL can be bothersome or scare away certain people
