At a Glance: Qt

Introduced in 1995, Qt is a versatile web application framework for developing cross-platform applications and graphical user interfaces (GUIs). If you’re looking to build an app that provides a seamless user experience (UX) across any device or operating system, an experienced Qt developer can help you launch your project.
Qt developers can use C++ to build applications that emulate the native GUI of Windows, Android, iOS, OS X, and other popular operating systems and platforms. They can take you through the process of UX concept design and Qt hardware adaptation to create a single code base for building multi-platform software, with the look and feel of native applications. More than a GUI or widget toolkit, Qt also provides abstractions for SQL databases, SVG, network sockets, OpenGL, XML, and Unicode. With bindings like PyQt or Jambi, developers can integrate the framework with languages like Python or Java. Qt developers on Upwork can bring true cross-platform functionality to your applications.
