@NewSense:

Yes, jPV has already help me on many parts on this project, i try to contact him when i need his help and he answer me each time.

Templario help me too for a project with graphics.

Beta-testers are a precious help too to improve this project

[EDIT]
GUI reworked a little, preview (fixed size in 320x256) take less place now and readme text is resizable in width with resize main window.
I think is better like this.
Balance object is possible for 2 objects "resizable", not possible in my GUI. I could down the buttons but i think it's not a good idea...
