Here is how to do it:

In your portlet's liferay-portlet.xml (you can check the DTD of this xml for more information on other tags) include two tags in your <portlet> tag as shown:

<portlet>
    <portlet-name>MyCustomPortlet</portlet-name>
    <icon>/mycustom.png</icon>
    <!--
        These are the two entries which are required for the portlet
        to appear in the control panel
    -->
    <!--
        Set the control-panel-entry-category value to "my", "content",
        "portal" or "server" to make this portlet available in the
        Control Panel under that category.
    -->
    <control-panel-entry-category>portal</control-panel-entry-category>

    <!--
       Set the control-panel-entry-weight value to a double number
       to control the position of the entry within its Control Panel
       category. Higher values mean that the entry will appear lower
       in the Control Panel menu.
    -->
    <control-panel-entry-weight>100</control-panel-entry-weight>

    <instanceable>false</instanceable>
    <header-portlet-css>/css/main.css</header-portlet-css>
    <footer-portlet-javascript>/js/main.js</footer-portlet-javascript>
    <css-class-wrapper>mycustomportlet-portlet</css-class-wrapper>
</portlet>

Also, if you don't want your portlet to appear in the Add Menu so that it is not put on other pages, then in your liferay-display.xml you can include:

<display>
    <category name="category.hidden">
        <!--
           Adding your portlet to the hidden category would not display
           the portlet in the ADD Menu on the top-left-hand corner
        -->
        <portlet id="MyCustomPortlet"></portlet>
    </category>
</display>

Build and deploy your portlet and you are good to go.

Apart from the Answer by Prakash K, ajaxable and instanciable should be false.
