A simple panel/taskbar unintrusive and light (memory / cpu / aestetic).
1. Update your package manager
2. In the ubuntu-precise-universe repo you will find tint2_0.11, be sure to examine the dependencies. libimlib2_1.4.4 (from the ubuntu-precise-main repo) should be found.
3. Install the packages
4. Done, now type tint2 in the console to start tint2 panel
tint2 will probably display under the jwm panel!
So you may need to open /.config/tint2/tint2rc in a text editor and change the panel_position parameter
