Port Xdialog from using GTK+ to FLTK

Additional Skills Required: Knowledge of GTK+ and FLTK. Project is to port the current version of Xdialog ([login to view URL]) to use FLTK instead of GTK+. The build options must include ability to static link individual components (e.g. Static link FLTK while libc uses the shared libraries). It must not have any dependency to GTK+. It must contain all standard items that are part of the original 'dialog' utility (listbox, buttons, checkboxes, etc..) and new standard controls such as combobox, spin box, etc.. Other items that are not part of the original "dialog" utility, and where there is no direct FLTK drop in replacement for the GTK widget, can be removed or commented out. The purpose is to reduce the size of the utility for use in lower memory environments like tinycore. The project will remain open source.
