QT App Development. Anyone ?

Is there any CEan who knows QT development ? I want to develop a QT based app for RPi which includes nothing but joystick like interface with Right-Left-Bottom-Top button and with acceleration & brake button. One more button to alter Motor ratio which is not mandatory.
I have developed few basic apps under QT using Docs available in KDE official site.
Is there anyone out here can help me ? I prefer that app does support XWayland/Wayland too, but that is among least priority task.
