Question : Linux Command Line GUI

Hi,
For the life of me, I cannot find how to create an interactive window that runs on the command line.

The best way I can describe it is, similar to the non-graphical installer for most linux distros; being a blue screen with options you can arrow around with.

(Similar to make-menuconfig for the kernel)

Any pointers would be greatly appreciated!

To expand on what I'm shooting for:
I want a user interface that can be used for configuring an app.
Afterwhich the app writes some config files (or executes some other scripts) and exits.
I don't have any strong C, C++, C# or Java background. But I do know bash, and bits of perl.

Possibly the dialog package is what you want. From the man page:

"Dialog is a program that will let you to present a variety of questions or display messages using dialog boxes from a shell script"

If you have it installed, you can read about it by typing "man dialog".
To get an appreciation of the look and feel, type "make menuconfig" instead of "make xconfig" in the Linux source directory.
dialog doesn't need X - it is an ncurses program.
