You can create email template in apex. The supported calls for an email template are as follows: create(), delete(), describeSObjects(), getDeleted(), getUpdated(), query(), retrieve(), update(), upsert().

The fields are: ApiVersion, Body (Type = textarea), BrandTemplateId, Description, DeveloperName, Encoding, FolderId, HtmlValue (Type = textarea), IsActive, LastUsedDate, Markup, Name, NamespacePrefix, OwnerId, Subject, TemplateStyle, TemplateType, and TimesUsed.

String NameVar; // holds name of email template
textarea BodyVar; // holds text body of email template 
Id BrandTmpIdVar; 
//Required - supplies letterhead information for the email template
String DevNmVar;
//This is the Label or Email Template's Unique Name.
Id FldrIdVar;
//ID of the folder that contains the template. Prob optional if you don't need to know this
String Sbjct; // holds subject of the Email Template

// Insert your code here to assign values to the above variables

// Now, create the email template

EmailTemplate e = New EmailTemplate(Name = NameVar, Body = Bodyvar, BrandTemplateId=BrandTmpVar, DeveloperName=DevNmVar, FolderId=FldrIdVar, IsActive=True, Subject=Sbjct, TemplateType=Text) ;

Insert e;
