Bode plot using GUI

Hi,

I am a beginner in Gui also to matlab with a matlab version of R2010b.

I have a transfer function H(s)= K*((s+a)*(s+b)) / ((s+c)*(s+d)*(s+e)*(s+f))
where s=jw
and want to be able to change the values of the parameters of a,b,c,d,e,f and the gain K using the Interface to get the bode plot of Magnitude and phase (2 plots) for different input parameters .
Also, must be able to change the M & N values for the transfer function.i.e N>=M

I have created an interface with default values for these parameters and the axes to obtain the 2 plots but not able to get the exact programming code to get it work.

Can anyone help me with this.
