Adding eCommerce to a Wappler Site

Since there doesn’t appear to be any way to build a shopping cart and integrate it with Paypal in Wappler, if I build a site in Wappler and then take it into DW to use the Sliding Paypal extension will I run into issues?

I have a site that I need to rebuild soon and I’d really like to use Wappler. Going back to DW is painful now.
