GUI programming question

[WipeOut]

Hi All..

I have a small project that needs a simple GUI app developped to 
simplify firing off complicated command lines..

Initially it will require a few variables to be typed in and then will 
have a few buttons that will perform some system tasks by running 
commands or scripts..

I have written bash scripts and some php in the past but never a desktop 
application..

There seems to be a huge choice of languages to do this like GTK, JAVA, 
QT and and a few others..

In looking briefly they all seem quite complicated but JAVA has the 
Netbeans development application which looks very useful for developing 
the GUI, just JAVA doesn't look that simple for the logic..

Whats the easiest way to do this for someone with very little 
programming experience??

TIA
