Yes it is possible. You just need to create a coff obj file and use the extrn directive to tell fasm the external symbols you want to use. Here is an example thats uses masm32's user32.lib, linked with ms link.exe.

Code:

 
format MS COFF

        extrn '__imp__MessageBoxA@16' as MessageBox

section 'data' data readable writeable
        msg db 'hello world', 0

section '.text' code readable executable

        public _start
_start:
        push 0
        push msg
        push msg
        push 0
        call dword [MessageBox]

        ret

Yes you can. That is what the examples in this thread demonstrate. But if you're having a problem someone here would be able to help you if you can provide more info.
