Logistic regression would appear to be the logical choice--assuming that you are trying to determine the probability of someone being in the No (or Yes) category given particular values on a set of predictors. There is no reason why you can't use multiple predictors.

Go to Analyze--Regresion--Binary Logistic

Enter your IVs as covariates. My understanding is that Base SPSS has the Logisitc procedure so you should not have any problems. I would strongly suggest you look at a good book on logistic regression before you start. Interpreting logistic regression results can be tricky. Try Hosmer and Lemeshow's Applied Logistic Regression.
