There is any way to create an standard input field on VF without bind it to an SObject field ?

I was searching on G unsuccessfully.

My approach was something like this:

<apex:inputField label="My Input" required="true" />

But I got this error:

value for <apex:inputField> is not a dynamic binding! 

Also,I've tried to assign a controller variable:

//class
public string myVar{get;set;}

//vp page
 <apex:inputField value="{!myVar}" required="true" />

Error:

Error: Could not resolve the entity from <apex:inputField> value binding '{!myVar}'. <apex:inputField> can only be used with SObject fields.

I need to add some inputs in order to make a filter using javascript. It is hard to believe for me that VF has not the option to make a simple input (resolving styling, labeling, etc)
