I intend to change certain features/functions in Emacs. I was wondering whether there is any feature in Emacs to popup a windows to show a warning message? Also, I would appreciate any alternative ideas if this feature is not available.
Cheers all.

You might also want to M-x apropos RET ^x- to find out about other GUI features emacs supports.
If you want something more sophisticated, you have to use/write separte programs.
Emacs GUI support is limited, but it interacts quite well with other processes.
