Yew is great but unrealistic for most UK bowyers.
Look for laburnum which is my favourite bow wood by far, but hard to find straight.
Wych Elm, sycamore, chestnut, dogwood, ash, hazel and more all make great bows and are readily available here in the UK.
Search for details of pyramid bows on paleo planet. A pyramid bow can be made out of almost any wood, even willow, and they are forgiving to make and shoot.
Oak is fine if you can get it, but not the simplest choice to start with.
No design is more or less likely to fail if properly tillered. Faults within the wood notwithstanding a broken bow is down to poor tiller or an inappropriate design for that species of wood.
A well tillered self bow of an appropriate design should last for years.
