The Qt API is implemented in C++, and provides additional features for easier cross-platform development. QML – introduced with Qt Quick and JavaScript-like declarative, language designed to describe the user interface of a program: both what it looks like, and how it behaves.  
Bindings to Qt exist for several other languages, including Python, Ring, Go, Rust, PHP, and Java™.
As an alternative to using C++, Qt offers other languages, including Python .
Officially, only the Python bindings are being maintained by the project, under the name of [https://pyside.org Qt for Python].

The Qt API is implemented in C++, and provides additional features for easier cross-platform development. QML – introduced with Qt Quick and JavaScript-like declarative, language designed to describe the user interface of a program: both what it looks like, and how it behaves. As an alternative to using C++, Qt offers other languages, including Python . Officially, Python bindings are being maintained by the project, under the name of Qt for Python.
