1. Qt is a cross-platform application development framework written in C++ that allows developers to write once and deploy applications across desktop and mobile platforms like Windows, Mac, Linux and embedded systems. 2. Qt provides modules for user interfaces, databases, networking, multimedia and more that have a common API design. It extends C++ with macros and introspection. 3. The presentation demonstrated a simple "Hello World" Qt application and introduced Qt Creator as the IDE for Qt development. It also covered signals and slots, stylesheets, deployment and the Qt Mobility APIs for mobile.
