How can i dissolve tungsten without using something like molten NaOH+KNO3...

Tungsten/Tunsten trioxide solubility
Dissolution of Tungsten by Hydrogen Peroxide
I doubt that concentrated H202 will be anymore easy to acquire.

I have done this before with 30% hydrogen peroxide. There are a couple of small issues if you go this route.
A soluble peroxytungstate ion can form. More details are available here: http://www.sciencemadness.org/talk/viewthread.php?tid=6862

Has anyone tried fenton reagent for dissolving the tungsten? Even with my 120vol H2O2 it's sooooo slow.

A recent discussion on tungsten that includes details on dissolution as well as some ideas on the use of the dissolved products.
