This can already be done with mIRC.
Use ktools.dll
Code:
on 1:START: {
  dll ktools.dll CreateSb .
  dll ktools.dll SbSetParts 100 200 300 -1
  dll ktools.dll SbSetText 0 > asdf > This
  dll ktools.dll SbSetText 1 > asdf > is
  dll ktools.dll SbSetText 2 > asdf > a
  dll ktools.dll SbSetText 3 > asdf > status bar.
}

[ pollstart]
[ polltitle=Would you like a statusbar for mirc? ]
[ polloption=Yes. ]
[ polloption=No. ]
[ polloption=I can't decide. ]
[ polloption=I don't understand what is this poll about. ]
[ pollstop ]

Try making the bit in italic, like [/ pollstop ].
But close the evaluation brackets.
The reason I spread them out is because if they was closed it'd evaluate the UBB code.
