Put other applications on Compiz widget layer?

[milstein]

I am wondering if I can put other application onto Compiz widget layer
e.g. /usr/local/bin/rainlendar2
By using the Desktop->Widget Layer->Behavior tab specifications

I did something like that for sticky_notes, but sticky_notes is a gnome applet itself. The following settings I've found on the forum works for sticky_notes
(class=Stickynotes_applet & (title=^0 | title=^1 | title=^2 | title=^3))

Thanks in advance!

Does anyone have some idea?
