Thais are allowed to have dual nationality, so there is no problem at the Thai end.

However, she cannot apply for British nationality, even though you have it, until she has satisfied the residency requirement. That is she must be free from any UK immigration control and, as the wife of a British national, have been resident in the UK for at least three years and during the three years prior to applying have spent no more than 270 days out of the UK with no more than 90 days in the final year.

She would also have to satisfy the Knowledge of language and life in the UK requirement.

So British nationality is out, unless you are prepared to move to the UK.

I don't know the rules on Spanish nationality, I'm afraid.
