making graphical user interfaces will likely scrare the pants of anyone who's attempting to get there from a nubile ground zero. dont be. zenity and yad are kinda revolutionising that stuff, expecially if you've already had the good sense to start getting some shell scripting savvy.

here's my initial foray (much thanks to statmonkey's scripts, which reading them made this all the more simple).
#!/bin/bash
#this is digit's first poke at zenity, dont expect much beyond hello world, ok.
zenity --question --title="zenjit rudimentary" --text="alo cosmos?" --ok-label="gosh, yes!"
ok, there you go. rudimentary ball rolling!
yeah, i know it doesnt really do anything yet... that will come next.
besides reading other people's zenity and yad scriptings, the man pages and help output is really useful too.

p.s.
added another line after that, in case that^ alone doesnt make it clear where to go from there.
zenity --question --text="there we go then" --ok-label="...k"
so you see... it's simple, just like script writing.
