Menu Customization

[gwaltgw]

I am trying to create a menu where there is a heading with the type of application it is followed by a horizontal row of icons of the actual applications. I'm hoping for it to look something like this:

Accessories
[icon][icon][icon][icon][icon]
Games
[icon][icon][icon][icon]
Graphics
[icon][icon]
Internet
[icon][icon][icon][icon]

etc ...

Is this possible in kde, lxde, xfce, or gnome2 ???

If it is, how do you do it? I know how to add/remove menu items and sub menus but that does not accomplish what I want.

If not, how close can I get to it?

I'm asking in this forum since i'm hoping to use ubuntu 10.04, xubuntu, lubuntu, etc ...

Thanks.
