This is possible: LyX has a mechanism called "external templates" which can be seen as a generalization of the graphics inset: With an external template, you can tell LyX what it needs to do to convert your STATA file into LaTeX, and you also tell it how this LaTeX is to be included in the LyX document. The only requirement for this to work is that your application (or any other tool) allows to convert to LaTeX from the command line. If you want to use this feature, you need to do two things: 1) Define a new external template for STATA as explained in chapter 6 "6 Including External Material" in the Customization Manual. This neds to be once, and if you need help don't hesitate to ask on the list. 2) Each time you want to include a STATA output, you use Insert -> File -> External Material. > I do that kind of stuff all the time.

LyX --export latex > tempfile.lyx;pdflatex tempfile.tex. This is certainly technically interesting, but I would not recommend such a procedure to the original poster, since the builtin mechanism does not need those helper scripts, and all the export/view buttons in LyX do just work.
