To write the binary (bsq) file itself is no problem. Just make sure that your array has the band dimension last (using TRANSPOSE if necessary), and write to disk:

A = fltarr(npixels, nlines, nbands)
openw, unit, 'myfile.bsq', /get_lun
writeu, unit, A
free_lun, unit

However, you must write code to dump the corresponding ENVI header file yourself. In simple cases this is rather easy, but a general solution is a lot of work.
