Running Dashboard widgets on Desktop

i am having trouble running a dashboard widget on my desktop. i have the program deeper and i have it working all set but here is where the problem lies.

when i place it on the desktop it puts it on top of everything. thats annoying as hell. how can i put it on the bottom layer of my desktop?

for example if i was in photoshop, its on the top layer, i need to put it on the bottom.

how do i go about doing this?

thanks!
