Your model will be estimable using -gmm- with panel/xt-style
instruments. It will probably be a lot of repetitive code that you
need to write macros for, though.

(Angry statalister's comment: frankly, you need to learn how to post
effective statalist questions, which is what Nick Cox wrote about some
two or three days ago. Your initial post was nearly uninformative, as
"nonlinear" is a vague term; what Maarten responded to was an often
taken stance that a non-linear model is anything that assumes a
non-linear link function, which is what -gllamm- is about.)
