See if one of the mouse utilities in the File Exchange will do what you want.

Also see the CurrentPoint property on the axes.

get(gca,'CurrentPoint')

It returns a 2x3 array because the axes actually shows a 3D volume. The first row is the point at the back of the volume, while the second row is the point at the front of the volume. In 2D the X & Y will be the same for both rows, you can just take the 1st row like this:

cpt = get(gca,'CurrentPoint')
pt = cpt(1,1:2)
