I would like to customize all the icons of my desktop environment, specially change Skype system tray icon which is very ugly! Can you tell me in which DE I can customize all the icons and use those that I prefer?

All DE's are capable of changing icon sets that you can download in their respective "Appearance", or "Look and Feel" menus. You can also manually change each one in file property windows by clicking the icon on the properties page, and choose any icon you want.
To specifically change only Skype's system tray icon, see the answer here : Change skype tray icon
