Thx for your response, Vampothika
This is the OS X Skin.

Those red, yellow, green buttons should be on the right side, because there will be some problems with the buttons on the left side in any programs (MS Office Suite for example)
I want buttons like a X for close and _ for minimize.... but without borders, you know, just the X and no 
Well, i want an old school skin, you know. A skin without any animations or transparency, like the windows classic scheme but with the look of OS X.
And the apple startbutton should be a black windows flag. So, i want a grey or maybe white skin with a blue mouse over button (see screenshot: Guest).
