You can get a basic interface by using \r to go to the beginning of the current line.
Slightly more advanced is ncurses.
The next step up is Newt.
If you want to do a GUI for Bash scripts or to wrap around other command line utilities, you can use dialog (man page).
Here two great dialog tutorial to get you started :
I wouldn't call wget's progress report as a 'nice gui', but anyway, the classic library for building graphical interfaces without X Windows is Linux and UNIX systems is ncurses.
Recently a C# version of ncurses has been started, check out details here
Try curses, it is a well documented API for text based UI.Also, there is so much open source projects that are using curses for you see and learn
wget does not really have a GUI, all I see is stuff that you can already achieve using stdout and echos (e.g. printf() or std::cout)
Anyways, for simple dialog boxes of the MessageBox kind, but not limited to that, also have a look at dialog
One should mention FTXUI. Functional Terminal (X) User interface: A simple C++ library for terminal-based user interfaces!
