Do any planets in the solar system, create tidal effects on the sun, similarly to the moon's effect of earth?

Yes, but it's very, *very* small.  

The reason is that while the tidal force scales linearly with the forcing body's mass, it also scales inversely as the distance *cubed*.

Let's scale our units so that the **Tidal Force of the Moon on the Earth = 1**. In those relative units, the rest of the planets' tidal forces on the Sun shake out as...

Planet | Planet/Moon mass ratio | Distance-to-Sun / Earth-Moon ratio| Relative Tidal Force
:--|:-:|:-:|:-:
Mercury|4.47|151|1.30 x 10^-6
Venus|66.3|282|2.96 x 10^-6
Earth|81.2|390|1.37 x 10^-6
Mars|8.74|593|4.19 x 10^-8
Jupiter|25800|2030|3.08 x 10^-6
Saturn|7730|3730|1.49 x 10^-7
Uranus|1180|7480|2.82 x 10^-9
Neptune|1390|11700|8.68 x 10^-10

In other words, **the largest tidal force on the Sun comes from Jupiter** (with Venus a close runner-up), and **it's 325,000x weaker than the tidal force exerted on the Earth by the Moon.**
