Have not posted for a long time. Am hoping to be more regular in future. Am currently working on a Perl based tool which will work on Solaris/Linux to show various information from /proc. Am currently looking at possible UI's for the tool. Have been looking a vxWindows bindings for Perl - looks quite good but there is not much in the way of documentation. Might look at TK/Perl - there is even an O'Reilly book on it. GUI program development is quite an education, very different from normal scripting, etc.
