minimize / restore / close buttons

[blux]

I wonder if there is a way to change the minimize / restore / close buttons
The visual styles i have are OS X. I searched everywhere but couldn't find how to change them. They look like in the image nr 1 ( round )
And i would like to have them like in the image nr 2 ( square )
Would you help me with some advices, please ?
Thank you

I tried many times to replace the buttons, but they look crap.
Would you help me, please ? I could upload my visual style if you want.
Thank you.
