Volume bar (hotkeys, KDE)

Question

Hello,
Is it possible to configure Arch (KDE) to display a nice bar with volume when I press my volume up, down hotkeys (the hotkeys are configured with acerhk module and codes added with xmodmap, KDE now recognise them). I remember I had something like this under ubuntu, but I don't know if it was a part of kde or something 'ubuntu specific'.

this script inc./dec (alsa) volume via amixer and shows a volume-bar via xosd (osd_cat).
#!/bin/bash
case $1 in
+)
amixer set PCM 2dB+
amixer set PCM 2dB-
exit
esac
VOLUME=`amixer get PCM | sed -ne '/Front Left/s/.*\[\(.*\)%\].*/\1/p'`
osd_cat --font -*-terminus-*-*-*-*-*-*-*-*-*-*-*-* --colour=Green --shadow 1 \
--pos bottom --align center --offset 80 --delay=1 -b percentage -P $VOLUME -T Volume
I use xbindkeys to run the script if I press  the vol. up or down keys on my keyboard.
This is the part for the volume keys of my .xbindkeysrc file (I saved the script as volume-xosd)
# PCM Volume up (Fn + up_arrow)
"/usr/local/bin/volume-xosd +"
c:176 + m:0x0
# PCM Volume down (Fn + down_arrow)
"/usr/local/bin/volume-xosd -"
c:174 + m:0x0
