Using JWM too. For having some basic desktop icons, added to .jwmrc:

<!-- Tray at the desktop. -->
<Tray layout="vertical" x="10" y="10" layer="0" border="0">
<TrayButton label="Programs"></TrayButton>
<TrayButton popup="netsurf" icon="netsurf.png">exec:netsurf</TrayButton>
</Tray>

<Tray layout="vertical" x="74" y="10" layer="0" border="0"> 
<TrayButton label="Tools"></TrayButton>
<TrayButton popup="urxvtc" icon="urxvtc.png">exec:urxvtc</TrayButton>
</Tray>

<Tray layout="vertical" x="138" y="10" layer="0" border="0">
<TrayButton label="Folder"></TrayButton>
<TrayButton popup="pcmanfm" icon="pcmanfm.png">exec:pcmanfm</TrayButton> 
</Tray>

@ eric
Sure, below is my conky.conf. Obviously, wifi interface (wlp1s0b1) should be changed as per your system. And conky.conf may be edited as you wish (for ex, {exec lscpu | grep 'Model name' | cut -c 22- | cut -d' ' -f1-4} may be replaced by its output in terminal). If you like haiku, just install fortune-mod-issa-haiku from AUR and make file conky1.conf for it.

Edit1: My conky.conf is updated to show MEM size (MiB) instead of %.
Also, a lot of stuff here > Arch conky configs and screenshots
