It isn't clear where you want to put the frame - maybe one of these does 
what you want:

Framed[Style[Binomial[n, j] == (n!/(j! (n - j)!) // HoldForm),
    FontFamily -> "Tahoma", FontSize -> 24, Bold]] // TraditionalForm

Style[Framed[Binomial[n, j]] == (n!/(j! (n - j)!) // HoldForm),
   FontFamily -> "Tahoma", FontSize -> 24, Bold] // TraditionalForm

Style[Binomial[n, j] == (n!/(j! (n - j)!) // HoldForm),
    FontFamily -> "Tahoma", FontSize -> 24, Bold] /.
   a_ == b_ -> Grid[{{a, b}}, Frame -> All] // TraditionalForm

More generally, you will find you get far more help here if you post 
some actual non-working code. Someone will almost certainly fix it for 
you, and explain what you were doing wrong.

 From your description, I can't even tell what items you want to put in 
a grid, but obviously you can put anything you like in a grid if you use 
the right syntax :) One way might be to start with a trivial grid and 
then replace the items with whatever you need, extending the 2D array as 
required:

Grid[{{a, b, c}, {d, e, f}}, Frame -> All]

If in doubt, the trick in Mathematica, is to start with something 
trivial or supplied in the help system, and progressively modify it to 
whatever you want.
