All I used for this is Apex Launcher, my own made wallpaper, and cold fusion icons.

Apex launcher: http://goo.gl/Lilqt
Wallpaper: http://goo.gl/K61XK
Cold Fusion icons: http://goo.gl/vO8tI

Apex launcher settings:

Homescreen settings~
-Portrait grid: 7 x 5 (Same with landscape)
-No Margin
-1 homescreen
- Uncheck ‘Show desktop indicator”
- Never show persistent search bar
- Hide notification bar, shadows, and icons labels.

You can do whatever in the drawer settings.

Dock settings~
-Scroll all the way down, and check “hide dock”

Now you can do whatever you want with all other settings.

I put some gesture like swipe down for notification bar, and more.
I also put some invisible icons like: app drawer, settings, battery info, and etc.
