Hi Walter, In addition to the the aforementioned GTK+, Qt, and wxWindows... There is OpenGL <http://www.opengl.org/>. A general purpose very powerful graphics library. There is SDL <http://www.libsdl.org/>. Simple DirectMedia Layer is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. There is SpriteWorld <http://www.spriteworld.org/>. An animation library intended to support games, but could be utilized for other non-game-writing purposes. Of the ones I have some familiarity, I recommend SDL. I'm personally not familiar with GTK+, Qt, and wxWindows. My co-workers who have at least some familiarity with them, speak highly of them. If you were looking just at MS-Windows, I'd still recommend SDL, rather than DirectDraw or GDI or GDI+ or Vista's WPF (Windows Presentation Foundation, codenamed "Avalon"). Or WinG (*cough*, yes, I programmed in WinG once upon a time). HTH, --Eljay
