yes you can.

just as you can import the maya commands you can import the Mel scripts

try  doing this

import maya.mel as mm
mm.eval("myMelScript;")

here is the part of the help docs from maya

Calling MEL from Python

To call MEL from Python, use the maya.mel.eval() function. It can do a better job of conversion than the MEL python command since Python has more flexible type support.

You must import the maya.mel module to use this command; that is:

import maya.mel as mm
mm.eval("polySphere;")

Or you can convert them to python with Pymel. Search topics for this.

dWin = window(title="Disperser", wh = (256, 256))
columnLayout()
button(label = "Disperse Selected!", command="disperse()")
text(label = "Set X Y Z Range Values")
rangeField = floatFieldGrp(numberOfFields=3)
showWindow(dWin)

using pymel is going to save you a *lot* of time when calling mel.
the alternative is a string formatting nightmare, especially if you
are passing arguments. with pymel you can call your mel script just
as you would any other python function.

instead of :
>>> mm.eval("myMelScript;")

you can just do:
>>> mel.myScript()

passed arguments will be formatted as well
