Book of Vaadin has a chapter for Valo theme: https://vaadin.com/book/-/page/themes.valo.html

If you are interested in the source code of the Valo theme demo, it should be found here https://github.com/vaadin/vaadin/tree/7.5/uitest/src/com/vaadin/tests/themes/valo

I have this:

package com.vaadin.ricardo.proyecto.mavenproject3;

import javax.servlet.annotation.WebServlet;

import com.vaadin.annotations.Theme;
import com.vaadin.annotations.VaadinServletConfiguration;
import com.vaadin.annotations.Widgetset;
import com.vaadin.server.VaadinRequest;
import com.vaadin.server.VaadinServlet;
import com.vaadin.ui.Button;
import com.vaadin.ui.Button.ClickEvent;
import com.vaadin.ui.CssLayout;
import com.vaadin.ui.HorizontalLayout;
import com.vaadin.ui.Label;
import com.vaadin.ui.Panel;
import com.vaadin.ui.UI;
import com.vaadin.ui.VerticalLayout;

/**
 *
 */
@Theme("mytheme")
@Widgetset("com.vaadin.ricardo.proyecto.mavenproject3.MyAppWidgetset")
public class MyUI extends UI {

    @Override
    protected void init(VaadinRequest vaadinRequest) {
        VerticalLayout contenedor=new VerticalLayout();
        contenedor.setSizeFull();
        CssLayout topbar=new CssLayout();
        Label lbl=new Label("Dashboard");
        lbl.setStyleName("h3");
        Button btn1=new Button("Home");
        btn1.setWidth("100%");
        Button btn2=new Button("Usuario");
        btn2.setWidth("100%");
        Button btn3=new Button("Settings");
        btn3.setWidth("100%");
        topbar.addComponent(lbl);
        topbar.addComponent(btn1);
        topbar.addComponent(btn2);
        topbar.addComponent(btn3);
        contenedor.addComponent(topbar);
        HorizontalLayout horizontal=new HorizontalLayout();
        horizontal.setSizeFull();
        Panel pCentro=new Panel("CONTENIDO");
        pCentro.setSizeFull();
        horizontal.addComponent(contenedor);
        horizontal.addComponent(pCentro);
        horizontal.setExpandRatio(contenedor, 20);
        horizontal.setExpandRatio(pCentro, 80);
               
        setContent(horizontal);

    }

    @WebServlet(urlPatterns = "/*", name = "MyUIServlet", asyncSupported = true)
    @VaadinServletConfiguration(ui = MyUI.class, productionMode = false)
    public static class MyUIServlet extends VaadinServlet {
    }
}

And the result is in the attachment image. But is Ugly :(

Check from https://github.com/vaadin/vaadin/blob/7.5/uitest/src/com/vaadin/tests/themes/valo/ValoThemeUI.java what styles the buttons use and how the menu is built. And from the theme css https://github.com/vaadin/vaadin/tree/7.5/WebContent/VAADIN/themes/tests-valo how the styles are defined.

EDIT: Valo demo sources might be actually here (at least according to vaadin.com/valo page https://github.com/vaadin/valo-demo)

You should set specifc style names etc. to achieve the look-and-feel of the left navigation. Maybe an easier example to follow is Matti's invoicer example application. Demo here http://matti.app.fi/invoicer/ and the source here https://github.com/mstahv/jpa-invoicer
