FVWM: How to makeup a system tray or something like it in the taskbar

[wint_chen]

All:
I don't know whether it's proper to list it here.
When I use Gaim or Input method in FVWM, I couldn't find where they are
when I minimize them.It was very inconvenient for me to work. So I hope
to have a system tray in the taskbar. Hope someone would help me to fix
this problem.Since I had looked over the manual of FVWM, I found nothing
about it.
Thanks
