Making a yew elb is not generally recommended for a beginner, but that being said, it's not impossible. The reason that most don't recommend starting with yew is price. A good yew stave is around $150 (last I saw) with osage being around $60 and hickory $40, that makes makes yew really expensive by comparison (not to mention harder to come by). Also yew is really thin ringed (harder to chase a ring on the back).
If your heart is set on a proper yew elb then I say go for it. Also, as longbowguy suggested, a tutor would a great help. Online help is great, but having someone there with experience is better.imho
Btw fwiw I have seen some fine elb's made from slippery (red) elm.
