How to adding new menu in magento admin panel

Here I have Created a new Module to Add new tab in admin panel of magento.
My Namesapce Name is Anjan and My Module name is Systab
As you know to make a module first we need to make a .XML file with Namespace_Module name under app/etc/modules/ folder. So My File name will be Anjan_Systab.xml

Now I will write the following code inside this xml

    
        
            true
            local
        
    
 

As My CodePool is local which is written in Anjan_Systab.xml I will create a Folder with name Anjan inside app/code/local/, then again will create another folder with name Systab inside Anjan Folder.Now I will create an etc folder inside the Systab Folder. Inside the etc folder I will create config.xml and will write the following code

    
        
            0.1.0
        
    
    
        
            
                standard
                
                    Anjan_Systab
                    systab
                
                                    
        
        
            
                
                    systab.xml
                
            
        
    
    
        
            
                admin
                
                    Anjan_Systab
                    systab

                        systab                    
                
            
        
        
            
                
                    Anjan_Systab
                
                
                    core_setup
                
            
            
                
                    core_write
                
            
            
                
                    core_read
                
            
        
        
            
                Anjan_Systab_Block
            
        
        
            
                Anjan_Systab_Helper
            
        
    
 

Now Clear your magento cache and login to you admin panel You can see one Tab Named My Tab has been successfully created.

Hope it Helps... Thanks....
