You cannot use javascript buttons in lightning.

I think the problem could be that "window.open" is not supported in lightning experience.

The following code should work but may not open the the URL in a new window. 
<input type="button" value="New Program" class="btn" onClick="createNewProgram();" title="New Marketing Program record"/>

function createNewProgram() {
  if( (typeof sforce != 'undefined') && sforce && (!!sforce.one) ) {
    sforce.one.createRecord('Marketing_Programs__c');
  }
  else {
    // Set the window's URL using a Visualforce expression
      window.open('{!URLFOR($Action.Marketing_Programs__c.New)}', '_new');
  }
}
I recomend checking out the Visualforce & Lightning Experience Trailhead Module (https://trailhead.salesforce.com/modules/lex_dev_visualforce) for more information on what I changed here. More specifily the 5th unit: "Manage Navigation (https://trailhead.salesforce.com/modules/lex_dev_visualforce/units/lex_dev_visualforce_navigation)".

Another option you can try which should open the URL in a new window is just to use an archor element or similar visualforce component 
<a href="{!URLFOR($Action.Marketing_Programs__c.New)}" class="btn" target="_blank" title="New Marketing Program record">New Program</a>
You may need to adjust some css to make the link look more like a button
