I am not ture if I understand you correctly, but if you just enter

D[f[x],x]  or Dt[f[x],x] and then (without evaluating !) use  
ConvertToTraditionalForm from the Cell menu you will get what you  
seem to be asking for.

However, I do not know of any way to convert the result of evaluating  
D[f[x],x] or Dt[f[x],x] (both are just f'(x)) to this form; in fact I  
do not think it is possible without some convoluted FrontEnd  
programming.
