Hi,

For creating a wizard first you can define a transient model in the system.

class TestReport(models.TransientModel):
    _name = 'test.report'

    date_from = fields.Date(string='From')
    date_to = fields.Date(string='To')

Then you can define the view in XML as follows,

<record id="view_test_report_wizard" model="ir.ui.view">
    <field name="name">Test Report</field>
    <field name="model">test.report</field>
    <field name="arch" type="xml">
        <form string="Choose The Details">
            <group>
                <group>
                    <field name="date_from" />
                    <field name="date_to"/>
                </group>
            </group>
            <footer>
                <button name="test_report" string="Print" type="object" class="oe_highlight" />
                or
                <button string="Cancel" class="oe_link" special="cancel"/>
            </footer>
        </form>
    </field>
</record>
