How to plot all real and complex roots of the following function in 3-
D using Manipulate by varying constant c?

q = 2.304 ;  z[c_,x_ ] = q Sin[ c x ] + c Sin[q x]. The real roots of
z[c] = 0 ( 0 < x < 20, 0 < real part of complex root < 20  ) should be
plotted on x-axis, complex conjugates on y -axis, and (x, z) plot is
in x -z plane where parameter c varies between  0.5 and 2.0

Thanks  in advance.
