No you don't have to go to the command line, but its faster.
Open two Konqueror windows
in one browse to the file.......ie: /usr/lib/java
in the other browse to where you would like to make your link.................ie: /usr/local/firefox/plugins
highlight the file
move to the intended destination
Konqueror should give you 3 choices
Pick link here
open a terminal
and type "ln -s /usr/lib/java/plugin /usr/local/firefox/plugins/plugin"
Of course replacing my examples with the real file locations.
