What is Qt?

Qt (qt.io) is a GUI toolkit used by programmers to create desktop applications. Qt is cross-platform: applications made with Qt can run on both Windows and Linux (and MacOS as well). It's the main competitor of GTK, a popular toolkit on Linux.

Screenshots

For reference, some screenshots of what Qt looks like:

A window titled [200] RSS Guard 4.7.4. In it, a left pane with a list of feeds in nested folders. A folder called "Labels" with an item "Interesting Articles" inside. A group called "Regex queries" with "(good|great) news" inside. An item for important articles, unread articles, and a recycle bin. On the right, two horizontal panes, one on top of the other: a tabular list of articles on the top, and the contents of the selected article at the bottom.
