Is it possible to create QT bindings for Xojo?

QT has many great controls, customization and tons more. QT also has bindings for Java and almost every other popular language.

So, is it possible to create QT bindings for Xojo (possibly with declares or external plugins)?

Are you referring to QT as in QuickTime? Because Apple will reject any app using QuickTime, and have essentially killed QuickTime as a video player.

I am referring to QT, the GUI/Widget framework

QT is a UI toolkit and Xojo has it’s own
Xojo lets you use the native toolkit for the OS and there are ways to add in new controls using a plugin but that involves writing a plugin.
I doubt anyone wants to write a QT plugin - it’d be massive.
