Hello Murad,
If your company is paying you to learn new skills, why would you decline? It is my experience that something that seems pointless to learn today, may come in handy just a few months or a few years later. At any given time, you are the captain of your (career)ship. But also at any given time, you need to keep that ship floating and attractive to employers. This can be done amongst others by adding new skills or maintaining others.
What's the worst that can happen? You don't like Qlikview (most unlikely), or the direction your career goes? Then make it known to the management and/or act upon it. At least, you've learned quite some things, and maybe can recover that or use it to learn another scripting language that suits you better.
However, if your heart is completely somewhere else (e.g. you want to become a vet), then quit now and follow that other dream.
