KaiView is a GUI toolkit/framework for writing applications using the TOM programming language. Based on a vector-oriented drawing layer using libart and freetype2, it provides a widget layer with subject/view separation, forms loaded from XML files, live updates to the GUI, Unicode support, abstract manipulator classes, antialiased everything, and a lot more.
WDialog is a system to make dialog-centric Web applications. It imitates the behavior of widgets found in GUIs, but acts in an HTML/HTTP environment. It uses its own XML-based UI language, but callbacks are coded in a normal programming language: either O'Caml or Perl. WDialog is written in Objective Caml, an ML variant.
GTK+-DirectFB is a backend for GDK, the drawing kit used by GTK+. Since DirectFB provides drawing functions, a windowing stack, and manages input devices, this is a lightweight GDK port. GTK+-DirectFB is based on GTK+-2.0 and implements the drawing functionality encapsulated in GDK. It allows you to run standard GTK+-2.0 applications on the Linux framebuffer. Due to the use of DirectFB, graphic operations are hardware accelerated if a suitable DirectFB gfx driver is available. Since DirectFB is a very thin library, the memory footprint of GTK+-DirectFB is relatively small.
