Hello every1

I am very new to Linux system,I don't know almost anything about it so I was thinking of asking this question from the experts

I recently downloaded the xPUD 0.9.2.
I LOVE that OS!It's simple,fast and smart

I just would like to add some other programs to it somehow.
Is that possible for ex. extracting the image,modifying files,then remaking the iso?(Talking in Windows7)
I would like to add some programs like Wine and some games also.
Please reply as soon as possible because the xpud site is down for bandwidth exceeded.
Thank you
