Are there any other cross-platform framework like Qt?

[grayfox]

Qt is great, but I am just wondering if there are any equivalent that are just as good

Yes, there are. If you need something lighter and faster than Qt look at this:

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation.
