wxWidgets

wxWidgets lets developers create applications for Win32, Mac OS X, GTK+, X11, Motif, WinCE, and more using one codebase. It can be used from languages such as C++, Python, Perl, and C#/.NET.

See that project here on ohloh for more history details. [Less]

Qt is a cross-platform application and UI framework. Using Qt, you can write applications once and deploy them across many desktop and embedded operating systems without rewriting the source code.

gtkmm

You can create user interfaces either in code or with the Glade User Interface designer, using libglademm. ... [More] There's extensive documentation, including API reference and a tutorial. [Less]

Fast Light Tool Kit

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX/Linux (X11), Microsoft Windows, and Mac OS X. It provides modern GUI functionality without the bloat, and supports 3D graphics via OpenGL and its built-in GLUT emulation. FLTK is designed to be small and modular ... [More] enough to be statically linked, and also works fine as a shared library. It also includes an excellent UI builder called FLUID that can be used to create applications in minutes. [Less]

wxGlade

Shoes

Shoes is a very informal GUI toolkit. It's for making regular old windowing apps. It's a blend of my favorite things from the Web, some Ruby style, and a sprinkling of cross-platform widgets.
