(I)∵Rt△ADE can be rotated by Rt△CAB, with point B corresponding to E and point A corresponding to D,

∴△ADE≌△CAB,

∴AD=CA=4,DE=AB=2,

∴OD=OA+AD= 1+4=5,

∴E point coordinates are (5,2);

∫A( 1,0),B(3,0),C( 1,4),

∴AC=4,

∴D(5,0),

∴ The vertical line of segment AD is x= 1+52=3, and the vertical line of segment AC is y=2.

∴q(3,2);

(II) The existence of such points T (72 72,0) and (52,0) can make △PEF a right triangle.

There are two situations:

(i) Let EF⊥AE intersect the X axis at F when △PFE takes point E as the vertex of right angle, as shown in figure 1.

∵△AED∽△EFD,

∴DFDE=EDAD= 12,

∴DF= 12DE= 1,

∴ point f (6 6,0),

∴ point t (72 72,0);

(2) When △ p ′ f ′ e takes point f ′ as the vertex of right angle, as shown in the figure.

∫△AED∽△EF′D,

∴df′de=dead= 12,

∴df′= 12de= 1,

∴ point f' (4,0),

Point t (52 52,0).

To sum up (1) and (2), it is known that the T coordinates of the points that meet the conditions are (72,0) and (52,0).
