Here is steps by what i guided:
1. Module declaration: Create new xml file in app/etc/modules/M4U_HelloWorld.xml
<?xml version="1.0"?> <config> <modules> <M4U_HelloWorld> <active>true</active> <codePool>local</codePool> </M4U_HelloWorld> </modules> </config>

1. Module configuration
   2.1. Create controller class in app/code/local/M4U/HelloWorld/controllers/IndexController.php

   class M4U_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action { public function indexAction() { $this->loadLayout(array('default')); $this->renderLayout(); } }

2.2. Create Block class in app/code/local/M4U/HelloWorld/Block/HelloWorld.php

class M4U_HelloWorld_Block_HelloWorld extends Mage_Core_Block_Template
                  {
                       // necessary methods
                  }

2.3. Create configuration xml in app/code/local/M4U/HelloWorld/etc/config.xml

<?xml version="1.0"?>
<config>
<global>
    <modules>
            <m4u_helloworld>
                    <version>0.1.0</version>
            </m4u_helloworld>
    </modules>
<blocks>
        <helloworld>
            <rewrite>
     <helloworld>M4U_HelloWorld_Block_HelloWorld</helloworld>
    </rewrite>
        </helloworld>
 </blocks>
    </global>
   <frontend>
            <routers>
                    <helloworld>
                            <use>standard</use>
                            <args>
                                  <module>M4U_HelloWorld</module>
                                  <frontName>helloworld</frontName>
                            </args>
                    </helloworld>
            </routers>
    <layout>
        <updates>
            <helloworld>
                  <file>helloworld.xml</file>
            </helloworld>
        </updates>
        </layout>
    </frontend>

1. Define frontend template
   3.1. Define page layout in app/design/frontend/default/default/layout/helloworld.xml
   <?xml version="1.0"?> <layout version="0.1.0"> <helloworld_index_index> <reference name="root"> <action method="setTemplate"> <template>page/1column.phtml</template></action> </reference> <reference name="content"> <block type="helloworld/helloworld" name="hello" template="helloworld/helloworld.phtml"/> </reference> </helloworld_index_index> </layout>

2. Create template file in app/design/frontend/default/default/template/helloworld/helloworld.phtml
